POLYAMIDE COMPOSITIONS FLAME RETARDED WITH ALUMINIUM HYPOPHOSPHITE

摘要

The present invention relates to a thermoplastic composition comprising at least aluminium hypophosphite (aluminium phosphinate), corresponding to the chemical formula Al(H2PO2)3 as halogen-free flame retardant agent, and at least a polymer based on polyamide. The flame retarded halogen-free thermoplastic moulding compositions according to the invention is used to produce articles based on polyamide polymers with or without glass fiber reinforcement, which are flame retarded.
