Preparation and Properties of Rigid Polyurethane-imide Foams Flame Retarded by Kaolin/APP

PI pre-polymerization method was adopted to synthesize the rigid polyurethane-imide (PUI) foams flame retarded by kaolin(KL) and APP. The effect of content and ratio of KL/APP on the limited oxygen index, smoke density rank, char layer morphology, density and mechanical properties was analyzed. The...
