Abstract
A composition useful for forming wire and cable insulation includes particular amounts of a poly(arylene ether), a hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene, a polyolefin, and a flame retardant. The flame retardant includes specific amounts of zinc borate, melamine cyanurate, and an organophosphate ester. The composition provides reduced cost and increased flexibility relative to known compositions using melamine polyphosphate and metal phosphinate flame retardants.
Claims18
A composition comprising:
- about 21 to about 40 weight percent of a poly(arylene ether);
- about 20 to about 45 weight percent of a hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene;
- about 2 to about 20 weight percent of a polyolefin;
- and
- about 11 to about 35 weight percent of a flame retardant comprising
- about 1 to about 10 weight percent of zinc borate,
- about 5 to about 20 weight percent of melamine cyanurate, and
- about 2 to about 15 weight percent of an organophosphate ester;
- wherein all weight percents are based on the total weight of the composition, unless a different weight basis is specified.
