Flammekasjerbare polyuretanskumstoffer

摘要

A polyether-polyurethane foam comprises the reaction product of polyisocyanate or polyisocyanate prepolymer(s) with polyether polyol(s), aliphatic chain extender(s) (optional), aromatic polyol component(s), and blowing agent comprising water. The aromatic polyol component is at least bifunctional. A polyether-polyurethane foam comprises the reaction product of: (A) polyisocyanate or polyisocyanate prepolymer(s); with (B) polyether polyol(s) having a functionality of 2-6 and a number average molecular weight of 1000-10000 g/mol; (C) aliphatic chain extender(s) of molecular weight 62-800 (optional); (D) an at least bifunctional aromatic polyol component(s); and (E) a water blowing agent; Independent claims are also included for: (1) a process for producing the polyether-polyurethane foam; and (2) a process for producing a composite material comprising laminating polyether-polyurethane foam layer with a textile or top layer.
