    Abstract: 1443117 Polyurethane foams HOECHST AG 8 Nov 1974 [9 Nov 1973] 48427/74 Heading C3R [Also in Division C2] Polyurethane foams are flame retarded by incorporating in the foam-forming mixture a polyol of Formula I where A is A 1 is B is Cl-CH 2 -CH 2 -O-, R is optionally halogen-substituted C 2-6 alkylene, phenylene or diphenylenemethane optionally substituted by alkyl or haloalkyl on the methylene C atom, one of R 1 and R 2 is H and the other is C 1-4 alkyl or haloalkyl or R 1 and R 2 are each C 1-4 alkyl or haloalkyl, x + y is 0À1 to 3 and n 1 or 2. In an example the polyurethane is formed from a partially branched polyether polyol based on propylene oxide and toluylene diisocyanate (80 : 20 blend of the 2,4- and 2,6- isomers).

    Abstract: Self-extinguishing laminates are made by an improved process, wherein individual layers of a carrier material are impregnated with a thermosetting phenolic resin containing a flame-retardant agent and the impregnated layers are placed one above another and bonded together by compressing them at elevated temperature and under elevated pressure to give a hardened laminate. More specifically, finely pulverulent phosphorus pentanitride as a flame-retarding agent is dispersed in the plasticized or non-plasticized thermosetting phenolic resin, with or without a diluent; the phenolic resin, based on its solid matter content, and the phosphorus pentanitride being used in an approximate ratio by weight of 100:4 to 100:15; and the phenolic resin, based on its solid matter content, and the carrier being used in an approximate ratio by weight of 100:80 to 100:150.

    Abstract: Intumescent flame-retardant coating composition consisting substantially of a film-forming agent, an ammonium polyphosphate, one or more substances which are carbonizable under the action of heat, a dispersant, and optionally a filler. The coating composition additionally contains an ammonium polyphosphate activator weighing 0.5 to 50% of the weight of ammonium polyphosphate. The activator is constituted by at least one salt which contains water of crystallization which is liberated upon the composition being heated to about 35 DEG C.
