Title (EN) POLYURETHANE COMPOSITES
(FR) COMPOSITES DE POLYURÉTHANE
Abstract:
(EN) The invention relates to a polyurethane composition, comprising: (1) an isocyanate; and (2) an isocyanate reactive compound; wherein the isocyanate comprises 2,2'-diphenylmethane diisocyanate and 2,4'-diphenylmethane diisocyanate, and the amount of 2,2'-diphenylmethane diisocyanate is in the range of 10-100wt% based on the total weight of 2,2'-diphenylmethane diisocyanate and 2,4'-diphenylmethane diisocyanate.The invention also relates to a polyurethane composite comprising said polyurethane composition and a reinforcing material, and an article produced from said polyurethane composite.
(FR) L'invention concerne une composition de polyuréthane comprenant : (1) un isocyanate ; et (2) un composé réactif à l'isocyanate ; l'isocyanate comprenant du 2,2'-diphénylméthane diisocyanate et du 2,4'-diphénylméthane diisocyanate, et la quantité de 2,2'-diphénylméthane diisocyanate est dans la plage de 10 à 100 % en poids sur la base du poids total de 2,2'-diphénylméthane diisocyanate et 2,4''-diphénylméthane diisocyanate. L'invention concerne également un composite de polyuréthane comprenant ladite composition de polyuréthane et un matériau de renforcement, et un article produit à partir dudit composite de polyuréthane.
