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 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.
