Flame retardant wood plastic composite

摘要

A wood plastic composite comprises a thermoplastic resin, a lignocellulosic filler, a flame retardant material in an amount of between 10 to 20 percent by weight, based on the total weight of the composite, and optionally other additives, wherein the flame retardant material comprises one or more compounds selected from the group of a cyclic organophosphorous compound and mixtures of the cyclic organophosphorous compound together with a nitrogen-containing organic compound, and optionally a minor amount of an inorganic flame retardant.
