PIR 聚异氰脲酸酯
Polyisocyanurate Foam
PIR聚异氰脲酸酯泡沫是由异氰酸盐经触媒作用后与聚醚发生反应制成之发泡材料,其物理防火性比一般聚氨酯发泡材料更为优异。
Polyisocyanurate foam is a kind of foaming material which can be made after the reaction of isocyanate, catalysis and polyether. It’s better than common polyurethane foam in physical properties and flame resistance.
