Abstract: The present invention relates to halogen-free flame retardant compositions, comprising polyolefins polymers as active ingredient and a flame retardant system. The flame retardant system comprises at least an Hypophosphorous acid metal salt (preferred is Aluminium hypophosphite) as main flame retardant component, at least a sterically hindered N-alkoxyamine with a specific structure as first flame retardant synergic component, at least a silicon oxide or aluminium oxide or a mixture thereof with specific properties as second flame retardant synergic component.

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.

Abstract: The invention disclose halogen free thermoplastic or cross linked polymers compositions comprising a polyolefin and/or a polyolefin containing polar co-monomers and a combination of metal hydroxides and inorganic hypophosphite as a synergic, and optionally other ingredients. These compositions show a superior balance of flame retardant properties compared to already known corresponding halogen free formulations. Molded items obtained using the polymer composition according to the present invention are useful in a wide range of injection molding and extrusion applications, especially cables.
