Abstract
A flame-retarded thermoplastic composition including a graft copolymer containing polyamide blocks and composed of a polyolefin backbone and on average at least one polyamide graft, in which the grafts are attached to the backbone by the residues of an unsaturated monomer (X) having a function capable of reacting with a polyamide, the residues of the unsaturated monomer (X) are attached to the backbone by grafting or copolymerization from its double bond, wherein the composition includes: —between 60% and 70% by weight of the graft copolymer containing polyamide blocks, —between 22% and 28% by weight of poly(pentabromobenzyl acrylate), —between 4% and 8% by weight of a synergistic flame retardant chosen from antimony trioxide, derivatives of tin, of molybdenum and/or bismuth and also boron and zinc oxides, calcium borates, calcium sulphate and/or zinc stannate, between 0.5% and 5% by weight of organophilic treated clay.
