Dahlia H. Salmah and O. Azlin School of Materials Engineering Universiti Malaysia Perlis UniMAP 02600 Jejawi Perlis Malaysia Corresponding author diary_omera84@ Abstract The effect of triethylene diamine TEDA as a catalyst and waste paper filler content on the properties of waste paper foam composites was investigated. The results indicate that an increase of waste paper filler content leads to an increased compressive strength elastic modulus and hardness. At constant waste paper content foam composites produced using the TEDA catalyst result in higher values of hardness compressive strength and elastic modulus compared to the waste paper foams produced without the aid of the catalyst. Keywords waste paper polyurethane foam catalyst composites Abstrak Kesan trietilena diamina TEDA sebagai pemangkin dan pembebanan yang berbeza daripada sisa kertas ke atas sifat-sifat komposit busa kertas telah dikaji. Keputusan menunjukkan dengan semakin meningkatnya kandungan sisa kertas maka kekuatan mampatan modulus elastik dan kekerasan meningkat. Pada kandungan sisa kertas yang sama komposit busa pemangkin menunjukkan nilai yang lebih tinggi terhadap kekerasan kekuatan mampatan dan modulus elastik dibandingkan busa sisa kertas tanpa pemangkin. Kata kunci sisa kertas busa poliuretena pemangkin komposit 1. INTRODUCTION Polyurethane foams are produced by the reaction of polyisocyanate polyol and water in the presence of a catalyst and other auxiliary agents. The polyurethane foam formation reaction essentially consists of a urethane reaction gelling and urea reaction blowing accompanied by the generation of CO2. However many complex reactions occur during the formation of a polyurethane foam. Catalysts play an important role in the control and balance between the gelling and blowing reactions. In addition to primary reactions the .
