Alumina trihydrate as flame retardant agent for urethane-modified carbodiimide-isocyanurate foams. |
摘要 |
Urethane-modified carbodiimide-isocyanurate foams are prepared by catalytically condensing (a) an organic polyisocyanate with a polyol or (b) a quasi-prepolymer in the presence of a blowing agent and from 20 parts to 100 parts by weight of alumina trihydrate. The resulting foams are characterized by improved flame retardancy without loss in strength properties. |
