Abstract

PROCEDE DE FABRICATION D'ELASTOMERES DE POLYURETHANES, THERMOSTABLES PAR INJECTION D'UN POLYISOCYANATE AROMATIQUE, D'UN POLYOL ET D'UN AGENT ALLONGEUR DE CHAINES DANS LA CAVITE D'UN MOULE. CE PROCEDE EST CARACTERISE EN CE QU'ON POST-VULCANISE L'ARTICLE DEMOULE A UNE TEMPERATURE DE 143 A 219C. LES PIECES DE POLYURETHANES MOULEES PAR INJECTION AVEC REACTION SONT UTILISEES DANS DIVERSES APPLICATIONS EN EXTERIEUR DE CARROSSERIE DANS DES AUTOMOBILES, OU LEUR FAIBLE POIDS CONTRIBUE A LA CONSERVATION DE L'ENERGIE.
