Abstract
A composition includes specific amounts of a poly(arylene ether), an unfunctionalized hydrogenated triblock copolymer, an unfunctionalized polyolefin, and magnesium dihydroxide. The composition is useful for forming insulation and sheath layers of wire and cable.
Claims47
A composition comprising:
- about 10 to about 35 weight percent of a poly(arylene ether);
- about 8 to about 16 weight percent of an unfunctionalized hydrogenated triblock copolymer of an alkenyl aromatic compound and a conjugated diene;
- wherein the unfunctionalized hydrogenated triblock copolymer has a weight average molecular weight less than or equal to 200,000 atomic mass units;
- about 15 to about 30 weight percent of an unfunctionalized polyolefin comprising about 14 to about 30 weight percent of an unfunctionalized ethylene-octene copolymer;
- and
- about 20 to about 60 weight percent of a magnesium dihydroxide;
- wherein all weight percents are based on the total weight of the composition.
