Abstract
Investigation of the thermal degradation of rigid urethane foams by means of TGA, DTA, infrared, and other techniques indicated that rigid foams prepared from a polyoxypropyl ene ether and a polymeric diphenylmethane type polyisocyanate began to decompose at ap proximately 210°C. Loss of weight occurred in two stages of approximately 50% each, oc curring at approximately 250-350°C and 400- 600°C. A similar pattern of decomposition was found for urethane foams based on a chlorinated polyester and the same polyiso cyanate. Addition of a reactive organophos phorous flame retardant to the polyoxypropyl ene ether foam lowered the temperature of initial decomposition to 150-170°C. The weight fraction of char formed at tempera tures above 400°C was increased, however.Keywords
