Abstract
The present invention relates to halogen-free flame retardant compositions essentially comprising polyamide polymers (preferred is PA6), at least an Hypophosphorous acid metal salt (preferred is Aluminum hypophosphite), at least an organic phosphinate metal salt (preferred is Aluminum Di Ethyl Phosphinate), at least a Nitrogen based flame retardant agent (preferred is Melamine Cyanurate), at least an organic polyhydric polymer (preferred is EVOH) and optionally further conventional components. Such compositions are highly flame retarded at low thickness and have high Glow Wire temperature resistance.
