Finnish stock market reaction to quarterly earnings announcements

This thesis examines the stock market reactions to quarterly earnings announcements. The study covers the OMX Helsinki 25 index companies for the years 2007–2010. The stock market response to quarterly earnings announcements is tested by employing the event study –methodology and daily stock returns of Finnish listed companies. The thesis provides evidence that stock prices react to earnings announcements that exceed or fall below analyst forecasts. The most liquid stocks earn higher returns around positive earnings news than less traded stocks, which supports the evidence from previous studies. This thesis finds evidence for the authorization to sell stocks short reducing the post–earnings announcement drift induced by negative earnings news. In addition, the market’s reaction to earnings announcements seems to quicken during economic turmoil.

Stock Market reaction to the CSR announcements of American fast food companies

The purpose of this study is to examine whether Corporate Social Responsibility (CSR) announcements of the three biggest American fast food companies (McDonald’s, YUM! Brands and Wendy’s) have any effect on their stock returns as well as on the returns of the industry index (Dow Jones Restaurants and Bars). The time period under consideration starts on 1st of May 2001 and ends on 17th of October 2013. The stock market reaction is tested with an event study utilizing CAPM. The research employs the daily stock returns of the companies, the index and the benchmarks (NASDAQ and NYSE). The test of combined announcements did not reveal any significant effect on the index and McDonald’s. However the stock returns of Wendy’s and YUM! Brands reacted negatively. Moreover, the company level analyses showed that to their own CSR releases McDonald’s stock returns respond positively, YUM! Brands reacts negatively and Wendy’s does not have any reaction. Plus, it was found that the competitors of the announcing company tend to react negatively to all the events. Furthermore, the division of the events into sustainability categories showed statistically significant negative reaction from the Index, McDonald’s and YUM! Brands towards social announcements. At the same time only the index was positively affected by to the economic and environmental CSR news releases.

Corporate Layoff Announcements and Shareholder Value: Empirical Evidence from Finland

Tutkimuksen tavoitteena on tutkia lyhyen aikavälin markkinareaktiota suomalaisten pörssiyhtiöiden irtisanomisilmoituksiin. Lisäksi tutkitaan poikkileikkausmenetelmän avulla, vaikuttavatko erilaiset yrityskohtaiset tekijät siihen miten osakemarkkinat suhtautuvat irtisanomisiin. Kolmantena tutkimuksen kohteena ovat maakohtaiset irtisanomisiin liittyvät tekijät sekä kuinka ekstensiivistä on yritysten tiedottaminen irtisanomisista. Aineisto sisältää 83 julkisesti annettua irtisanomistiedotetta viiden vuodenaikaväliltä (kesäkuu 2000 - kesäkuu 2005). Osakemarkkinoiden keskimääräistä reaktiota sekä kehitettyjä alihypoteeseja tutkittiin hyödyntämällä tapahtumatutkimusmetodia. Empiiriset tulokset osoittavat, että sijoittajat näkevät irtisanomisetkeskimääräisesti negatiivisina uutisina yhtiöiden markkina-arvon kannalta. Irtisanomisilmoituksia edeltävä markkinareaktio on negatiivinen tukien aiempia tutkimustuloksia Yhdysvaltojen ja Iso-Britannian markkinoilta. Erona aikaisempiin tutkimuksiin on kuitenkin se, että negatiivinen markkinareaktio on täysin hinnoiteltu jo ilmoitusta edeltävänä aikana. Tukea löytyi myös kaikille yrityskohtaisillealihypoteeseille, jotka selittävät sijoittajien reaktiota irtisanomisilmoituksiin: koko pääoman tuotto, suhdannesykli, corporate governance sekä yrityksen ja johdon maine.

Project Success through Effective Decisions: Case Studies on Project Goal Setting, Success Evaluation and Managerial Decision Making

The objective of the thesis is to structure and model the factors that contribute to and can be used in evaluating project success. The purpose of this thesis is to enhance the understanding of three research topics. The goal setting process, success evaluation and decision-making process are studied in the context of a project, business unitand its business environment. To achieve the objective three research questionsare posed. These are 1) how to set measurable project goals, 2) how to evaluateproject success and 3) how to affect project success with managerial decisions.The main theoretical contribution comes from deriving a synthesis of these research topics which have mostly been discussed apart from each other in prior research. The research strategy of the study has features from at least the constructive, nomothetical, and decision-oriented research approaches. This strategy guides the theoretical and empirical part of the study. Relevant concepts and a framework are composed on the basis of the prior research contributions within the problem area. A literature review is used to derive constructs of factors withinthe framework. They are related to project goal setting, success evaluation, and decision making. On the basis of this, the case study method is applied to complement the framework. The empirical data includes one product development program, three construction projects, as well as one organization development, hardware/software, and marketing project in their contexts. In two of the case studiesthe analytic hierarchy process is used to formulate a hierarchical model that returns a numerical evaluation of the degree of project success. It has its origin in the solution idea which in turn has its foundation in the notion of projectsuccess. The achieved results are condensed in the form of a process model thatintegrates project goal setting, success evaluation and decision making. The process of project goal setting is analysed as a part of an open system that includes a project, the business unit and its competitive environment. Four main constructs of factors are suggested. First, the project characteristics and requirements are clarified. The second and the third construct comprise the components of client/market segment attractiveness and sources of competitive advantage. Together they determine the competitive position of a business unit. Fourth, the relevant goals and the situation of a business unit are clarified to stress their contribution to the project goals. Empirical evidence is gained on the exploitation of increased knowledge and on the reaction to changes in the business environment during a project to ensure project success. The relevance of a successful project to a company or a business unit tends to increase the higher the reference level of project goals is set. However, normal performance or sometimes performance below this normal level is intentionally accepted. Success measures make project success quantifiable. There are result-oriented, process-oriented and resource-oriented success measures. The study also links result measurements to enablers that portray the key processes. The success measures can be classified into success domains determining the areas on which success is assessed. Empiricalevidence is gained on six success domains: strategy, project implementation, product, stakeholder relationships, learning situation and company functions. However, some project goals, like safety, can be assessed using success measures that belong to two success domains. For example a safety index is used for assessing occupational safety during a project, which is related to project implementation. Product safety requirements, in turn, are connected to the product characteristics and thus to the product-related success domain. Strategic success measures can be used to weave the project phases together. Empirical evidence on their static nature is gained. In order-oriented projects the project phases are oftencontractually divided into different suppliers or contractors. A project from the supplier's perspective can represent only a part of the ¿whole project¿ viewed from the client's perspective. Therefore static success measures are mostly used within the contractually agreed project scope and duration. Proof is also acquired on the dynamic use of operational success measures. They help to focus on the key issues during each project phase. Furthermore, it is shown that the original success domains and success measures, their weights and target values can change dynamically. New success measures can replace the old ones to correspond better with the emphasis of the particular project phase. This adjustment concentrates on the key decision milestones. As a conclusion, the study suggests a combination of static and dynamic success measures. Their linkage to an incentive system can make the project management proactive, enable fast feedback and enhancethe motivation of the personnel. It is argued that the sequence of effective decisions is closely linked to the dynamic control of project success. According to the used definition, effective decisions aim at adequate decision quality and decision implementation. The findings support that project managers construct and use a chain of key decision milestones to evaluate and affect success during aproject. These milestones can be seen as a part of the business processes. Different managers prioritise the key decision milestones to a varying degree. Divergent managerial perspectives, power, responsibilities and involvement during a project offer some explanation for this. Finally, the study introduces the use ofHard Gate and Soft Gate decision milestones. The managers may use the former milestones to provide decision support on result measurements and ad hoc critical conditions. In the latter milestones they may make intermediate success evaluation also on the basis of other types of success measures, like process and resource measures.

Vesikiertoisen ja kaapeleilla toteutetun lattialämmityksen teknistaloudellinen vertailu

Lopputyössä vertailtiin vesikiertoisen ja kaapeleilla toteutetun lattialämmityksen erilai-sia ominaisuuksia. Vertailuparametreinä olivat lattialämmitysten mitoitus, säätö, asen-nus, investointikustannukset, käyttökustannukset, vikaantuminen ja korjaus, asumis-viihtyvyys, käyttöön liittyvät tekijät, markkinat ja toimijat sekä lattian päällysteet. Näistä lat-tialämmityksien asumisviihtyvyys, säätö ja kustannukset otettiin tarkempaan vertailuun. Lämmitysjärjestelmien kokonaiskustannuksia vertailtiin 25 vuoden jaksolla ja 4 % ko-rolla. Investointikustannuksiin sisältyi lämmitysjärjestelmien lisäksi lkv-varaajan ja tek-nisen tilan kustannukset sekä liittymismaksut. Käyttökustannusten vertailussa otettiin huomioon lämmityskulujen lisäksi myös lämmityksen hyötysuhde, yö- ja päiväsähköosuudet ja -energian hinnat, taloussähkön kustannukset, perusmaksut sekä huoltokulut. Tutkimuksen mukaan halvin pientalojen lämmitysmuoto on osittain varaava huonekoh-tainen sähkölämmitys, jonka vuosittaisiksi kustannuksiksi tuli 11452 mk. Sähkölämmi-tyksen tekee vertailtavista halvimmaksi lämmitysjärjestelmäksi pientaloille (n. 150 m2) sen pienet pääomakustannukset, lämmityksen hyvä hyötysuhde sekä varsin kilpailuky-kyiset käyttökustannukset. Vertailun kallein oli öljyä energialähteenä käyttävä vesikiertoi-nen lattialämmitys, jonka vuosittaisiksi kustannuksiksi tuli 13080 mk. Öljy on energia-hinnaltaan halpa, mutta öljylämmityksen huono hyötysuhde sekä varsin korkeat pää-omakustannukset tekevät siitä vertailtavista kalleimman lämmitysmuodon. Energian hin-tojen herkkyysanalyysissä huomattiin sähkön säilyttävän kilpailukykynsä, vaikka öljyn ja maakaasun hinnat laskisivatkin huomattavasti. Asumismukavuuden ja säädön kohdalla vertailtiin lämpötilojen tasaisuutta huonetilois-sa. Mittauskohteiden huonelämpötiloja on seurattu eri projekteissa jatkuvatoimisesti jo-pa yli kahden vuoden ajan. Mittaustulosten mukaan vesikiertoisella lattialämmityksellä huonelämpötilat ovat tasaisemmat kuin osittain varaavalla huonekohtaisella sähköläm-mityksellä. Tämä johtuu sähkölämmityksen varaavuudesta. Hyvillä yhdistelmätermostaateilla päästään tosin myös huonekohtaisen sähkölämmityksen yhteydessä tasaisiin huonelämpötiloihin. Molempien lämmitysmuotojen säädön heikkoutena on hidas reagointi sisäisten lämmönlähteiden aiheuttamaan nopeaan sisälämpötilan nousuun.

Omien osakkeiden hankinta Suomessa

Tämän tutkielman päätavoitteena on ollut selvittää omien osakkeiden hankintaa ja hankintatarkoituksien järkevyyttä Suomessa, sekä tutkia aikaisempien empiiristen tutkimusten avulla, onko omien osakkeiden hankinta perusteltua myös osakkeenomistajien kannalta. Lisäksi tutkielman tavoitteena on nostaa esille sellaisia näkökohtia ja säännöksiä, joita osakkeenomistajien ja yritysjohdon tulisi painottaa ja ottaa huomioon tehdessään omien osakkeiden hankintapäätöksiä. Tämän tutkimuksen tutkimusmetodologia mukailee hyvin pitkälti käsiteanalyyttista tutkimusotetta. Tutkimuksen johtopäätökset ovat lähinnä toteavia ja suosittelevia. Empiria tulee mukaan käsiteanalyyttiselle tutkimusotteelle tyypilliseen tapaan eli aikaisempien jo olemassa olevien empiiristen tutkimusten muodossa.Suomessa omien osakkeiden hankinnasta saavutetut hyödyt eivät ole osakkeenomistajien kannalta aivan yhtä helposti saavutettavissa kuin Yhdysvalloissa. Suomessa omien osakkeiden käyttö vaihtoehtoisena voitonjaon keinona on osakkeenomistajien kannalta verotuksessa huonompi vaihtoehto kuin osingot. Tällä hetkellä omien osakkeiden hankinta on pikemminkin yhtiön keino rahoittaa yrityskauppoja, henkilökunnan optiojärjestelyjä, siistiä tasetta, jakaa ylimääräisiä kassavaroja osakkeenomistajille ja yritys vaikuttaa osakekurssiin. Omien osakkeiden hankinta on mahdollista toteuttaa Suomessa osakkeenomistajia hyödyntävällä tavalla, mutta omien osakkeiden hankintamenettelyä on kehitettävä mm. tekemällä todellisia omien osakkeiden hankintoja ja esittämällä hankintatarkoitukset luotettavammin. Empiiristen evidenssien mukaan omien osakkeiden hankinta esimerkiksi julkisella ostotarjouksella markkinahintaa korkeampaan hintaan voisi edesauttaa johdon välittämän ”sisäpiiritiedon” ymmärtämistä myös Suomessa.

Osakekurssin reagointi tulosvaroitukseen nousu- ja laskumarkkinoilla

Tutkimuksen tavoitteena on selvittää tapahtuuko tulosvaroituksen yhteydessä yli- tai alireagointia nousu- ja laskumarkkinoiden aikana. Tutkimus tehdään tapahtumatutkimuksena, jossa tarkoituksena on tutkia osakkeiden epänormaaleja tuottoja tulosvaroituspäivän ympärillä. Tapahtumaikkunan pituus on yhteensä 11 päivää [-5, +5]. Aineisto koostuu Helsingin pörssin OMXH25 indeksin yritysten julkaisemista tulosvaroituksista vuosien 1997–2009 välillä. Tälle aikavälille osuu 200 päivän liukuvalla keskiarvolla mitattuna kaksi nousu- ja kaksi laskumarkkinaa. Tutkimuksessa ei havaittu selvää yli- tai alireagointia nousu- tai laskumarkkinoilla. Sen sijaan tietty säännöllisyys reagoinnissa tulosvaroituksiin löydettiin: Nousumarkkinoilla, tulosvaroituspäivän jälkeen näkyy selvä positiivinen tuotto kahden päivän ajalta tulosvaroituksen jälkeen, riippumatta siitä onko kyseessä positiivinen vai negatiivinen tulosvaroitus. Vastaavasti laskumarkkinoilla löydettiin selvä negatiivinen epänormaali tuotto kahden päivän ajalta tulosvaroituksen jälkeen.

Ikääntyvät työelämässä. Päihittääkö nuoruus ja koulutus aikuisuuden ja kokemuksen?

The Ageing in Working Life. Do Adolescence and Schooling Beat Adulthood and Experience? This study examines the changes in the work and the work organisations of employees in the fields of health care and retail trade who have turned 45 and their experience of change. In addition, the question of how ageing employees experience their status in post-modern working life is explored. Attention is also focused on the choices and decisions connected with staying at work and retiring. These views are examined in relation to professions and professional cultures. Thematic interviews (N=98) were used to gather the material. The effects of the market liberalistic turn in welfare policy are clearly seen in the everyday work of the health care professions. These changes were examined from the point of view of managing by outcomes and quality assurance, multi-professional cooperation, flexibility in the division of labour, and the spread of market-like procedures. The discourse of those in involved retail trade was dominated by extremely tight global market competition and control of outcomes, and by the structural changes taking place in the retail trade sector. This change discourse was to a large extent a reaction to those changes in the functional environment which were experienced as negative and to the conflict between their own professional identity and professional ethics on the one hand, and their functional environment on the other. There were also obstacles connected with professional culture: defending one's own station and power, guarding the 'frontier', showed up in attitudes towards new management and organisation models or towards structural and functional reforms. The deep structures of professional culture and the mindset of the actors change much more slowly than the functional practices of organisations. For those in a supervisory position, the loss of power due to becoming part of a chain or because of the introduction of a team organisation model was not an easy thing to accept. The nurses and others in related fields felt that they were forced to do work that was below their level of training and professional skill. For sales personnel and those who did assisting work in health care, power and the possibility of having an influence were not so important, as long as they were able to do their work in their own way and were trusted. This view is often completely forgotten, for example, in various organisation models in which power and the possibility of having an influence entwined with power are taken for granted as being clearly positive and desired aspects of job satisfaction. Up to date professional skills were experienced as being important from the point of view of professional identity and self-worth. Thus, training can be understood as a moral obligation, which in turn is intertwined with professional ideology. In the rhetoric of adult education, an adult is expected to be an active player who will seek training again and again if working life so requires. The dark side of this ideology, which leads to feelings of guilt, was apparent in the thoughts of the respondents. Am I never good enough at my job; why must I continually strive for better, additional qualifications? The majority of the respondents evaluated their expertise as being at quite a high level. This self-confidence did not extend to applying for a job. Job recruitment was seen as a situation in which age discrimination reached its peak. The interviewees were unanimous about the idea that society favours the young. Especially among those in the retail trade sector, there was a feeling that it would be difficult, if not impossible, to find a new job of the same level or a permanent post if they were made redundant. Age discrimination was also apparent in the retail trade field in the form of older employees being retired against their will or transferred to other tasks. It was felt that ruthless forced retirement of older workers was part of the personnel policy of some organisations. The importance of one's outward appearance was connected with the theme of discrimination. This phenomenon is described using the concept of the double standard of ageing in feminist research. An ageing woman is relegated to an inferior position due to both her age and her sex. A culture that would both make possible and allow various types of choices regardless of age, which is described as being characteristic of the post-modern era, does not seem to be very topical in the practice of working life. It is important for employees that the management and the personnel policy that is being implemented makes them feel like both their contribution and they as individuals are appreciated, that their opinions are listened to and that they are noticed as persons. The interviewees hoped for gratitude and a concern for the well-being of employees that shows in everyday life. They valued training and activities aimed at maintaining their work ability, but thought that better coping at work and a pleasant working environment cannot be achieved through such measures as along as the foundation is 'in a mess'. Development of the quality of working life is the only thing that can improve job satisfaction and get people to remain in the work force longer than at present. There should be a sufficient number of properly trained employees at the work place. It was important to the respondents that they be able to stay on their job to the end with honour, since compromising with their own quality standards or acting contrary to their ideal self-image in terms of professional ethics would strike a blow to their professional self-esteem. They called for the development of various types of workplace flexibility, and felt that they have the right to a lightened workload and to early retirement. Early retirement was even seen as an altruistic deed: it would free up a place for younger workers. Thoughts of retirements were explained by familiar factors such as health and finances, life situation, the enticement of free-time, as well as by various factors related to work. It is very important to ageing employees that their work has meaningful content. The values related to self-fulfilment are felt to be of great importance, and if they cannot be realised at work, the respondents wanted more free time, either through retirement or in the form of flexibility in working life.

Hitsauksen aiheuttamat muodonmuutokset ja niiden hallinta alumiiniveneiden rakenteissa

Alumiiniveneissä hitsauksen aiheuttamat muodonmuutokset ovat usein erittäin haitallisia, koska niiden aiheuttamat mittamuutokset ja ulkonäölliset haitat alentavat tuotteen laatua sekä arvoa. Monissa tapauksissa myös hitsausliitoksen suorituskyky heikentyy ja lisäksi hitsausmuodonmuutokset voivat aiheuttaa toiminnallisia ongelmia alumiiniveneiden runkorakenteisiin. Tästä johtuen hitsausmuodonmuutosten hallinta ja minimointi ovat erityisen tärkeitä tekijöitä pyrittäessä parantamaan alumiiniveneiden laatua ja kustannustehokkuutta sekä kasvattamaan alumiinivenealan kilpailukykyä. Tässä diplomityössä tutkittiin robotisoidun kaasukaarihitsauksen aiheuttamia muodonmuutoksia sekä niiden hallintaa alumiinista valmistettujen työ- ja huviveneiden runkorakenteissa. Työssä perehdyttiin nykyaikaiseen alumiinivenevalmistukseen sekä hitsattujen rakenteiden yleisiin lujuusopin teorioihin ja käyttäytymismalleihin. Alumiinin hitsausmuodonmuutosten tutkimuksissa suoritettiin käytännön hitsauskokeita, joiden kohteina olivat alumiiniveneissä käytetyt rakenneratkaisut ja liitostyypit. Työn tavoitteena oli määrittää alumiinin hitsauksessa syntyviin muodonmuutoksiin keskeisesti vaikuttavia tekijöitä ja parametreja. Tutkimustulosten perusteella pyrittiin esittämään ratkaisuja alumiiniveneiden rakenteisiin aiheutuvien hitsausmuodonmuutosten vähentämiseksi ja hallitsemiseksi. Alumiinirakenteissa hitsausmuodonmuutokset ovat hyvin tapauskohtaisia, koska usein niiden syntyminen määräytyy monen tekijän yhteisvaikutuksesta. Teräsrakenteille käytetyt yleiset analyyttiset laskentakaavat ja käyttäytymismallit eivät sovellu suoraan alumiinirakenteille, mikä johtuu alumiinin erilaisista materiaaliominaisuuksista ja käyttäytymisestä hitsauksen aikana. Tulevaisuudessa empiiristen koejärjestelyiden ja analyyttisten mallien lisäksi sovellettavan numeerisen elementtimenetelmän avulla voidaan parantaa alumiinin hitsauksessa aiheutuvien muodonmuutosten kokonaisvaltaista hallintaa.

Employee layoff announcements and shareholder wealth: empirical evidence from Finland 2008-2013

This thesis investigates the short-term stock price reaction to layoff announcements in Finland. It also studies whether the characteristics of the firm or the layoff announcement have an impact on the stock market reaction. Standard event study methodology was utilized to examine the stock price reactions to layoffs and to test the created hypotheses. The event pool consisted of 102 publicly disclosed layoff announcements that were announced during the time period from June 2008 to December 2013. The empirical results show that the stock market reaction is strongly positive in the pre-event period of -10 to -1 with CAAR of 2,69%. The reaction is however slightly negative on the event date with AAR of -0,57%. Based on the results the conclusion is that either the managers are timing the markets or the layoffs are seen as efficiency improving acts and the market becomes aware of such actions pre-event. Additionally different characteristic hypotheses are tested to find out whether they would explain the reaction. The characteristics are: the reason stated by the management, business cycle, industry group, prior performance, leverage-ratio, the size of the company, the size of the layoff and the duration of the layoff.

Paul and death : a study in psychological coping

The present investigation looks into the attitudes toward death in Paul’s authentic letters, and puts them in relation to modern theories of psychological coping. Drawing on psychologically-oriented hermeneutic theory, and theories about psychological coping in particular, I argue that each case of psychological coping must be understood in its historical situation as strategies emanating from a specific person’s subjective appraisal (cf. Pargament, Lazarus and Folkman). Paul’s letters frequently refer to persecution and violent death. To aid in psychological coping is often integral to the purpose of the letters, which makes the perspective of psychological coping akin to their genre. In the course of a tentatively assumed chronological order of 1 Thessalonians, Galatians, 1 Corinthians, 2 Corinthians, Romans, Philippians, and Philemon, Paul moves from the perception of Jesus dying for the faithful to the understanding of dying with Jesus. His coping strategies concerning death are gradually transformed from conservative and deferring coping styles, to a more self-directing coping style, to collaborative and transformative coping styles, and finally to a new sense of deferring coping style in prison. The last case of deferring coping carries the traits of generosity and flexibility even in the face of death, which is in contrast to his previous letters. Through his correspondence, we see Paul’s attitude toward death transformed from denial to reaction, to processing, to acceptance (cf. Lindemann, Kübler-Ross, Bowlby, Parkes, among others). His strategies also shift in accordance with these understandings. Denial is accompanied by diversion, threat by aggression, processing by rumination, and acceptance by joy. The study shows the hermeneutic benefits of reading Paul’s letters as the rhetorically framed expressions of a person in a particular historical situation. The letters open small windows through which we can glimpse the coping process of a person of antiquity. In adopting the method of psychological exegesis, the study shows that the variety of attitudes toward death in Paul’s letters makes sense from the perspective of psychological coping. The psychological aspect of these letters is an underexamined richness that can extend into areas of contemporary individual and group identity, and from there to public policy and ethics.

Foreign Direct Investment and Shareholder Wealth Gains: Evidence from Finnish FDI in China

In Finnish discourse, “The China Effect” refers to the surge of offshoring activities by Western companies to China during the past couple of decades. Inspired by event studies concerning announcements of foreign direct investment, this thesis investigates the market’s reaction to Finnish companies’ announcement of FDI targeting the People’s Republic of China. Standard event study methodology is applied to 135 announcements related to subsidiaries, joint ventures and acquisitions between 1997 and 2014. The data is checked for contamination by unrelated coinciding events and outliers. A positive average abnormal return is found to take place on the date of the announcement. Additionally, the abnormal returns are found to exist only for projects announced before 2008, and only when the investment project is new, as opposed to investments made to extend previously established projects. Ownership arrangement and the novelty of facilities do not influence the market’s reaction towards the investment announcement.

Improving the fire retardancy of extruded/coextruded wood-plastic composites

The main objective of this thesis is to study the impact of different mineral fillers and fire retardants on the reaction-to-fire properties of extruded/coextruded wood-plastic composites (WPCs). The impact of additives on the flammability properties of WPCs is studied by cone calorimetry. The studied properties are ignition time, peak heat release rate, total heat release, total smoke production, and mass loss rate. The effects of mineral fillers and fire retardants were found to vary with the type of additive, the type of additive combinations, the amount of additives, as well as the production method of the WPCs. The study shows that talc can be used to improve the properties of extruded WPCs. Especially ignition time, peak heat release rate and mass loss rate were found to be improved significantly by talc. The most significant improvement in the fire retardancy of coextruded WPCs was achieved in combinations of natural graphite and melamine. Ignition time, peak heat release rate and total smoke production were improved essentially. High increase in smoke production was found in samples where the amount of ammonium polyphosphate was 10% or higher. Coextrusion as a structural modification was found as a promising way to improve the flammability properties of composite materials in a cost-effective way.
