Abstract:
1. An electrical wire comprising: a conductor; and a covering disposed over the conductor wherein the covering comprises a thermoplastic composition and the thermoplastic composition comprises: (i) a poly(arylene ether); (ii) a polyolefin; (iii) a block copolymer; and (iv) a flame retardant wherein the electrical wire has an abrasion resistance of greater than 100 cycles, as determined by the scrape abrasion specification of ISO 6722 using a 7 Newton load, a needle having a 0.45 millimeter diameters, and an electrical wire having a conductor with a cross sectional area of 0.22 square millimeters and a covering with a thickncss of 0.2 millimeters, and wherein the thermoplastic composition has a tensile elongation at break greater than 30% as determined by ASTM D638-03 using a Type I specimen and a speed of 50 millimeters per minute, and a flexural modulus less than 1800 Megapascals (Mpa) as determined by ASTM D790-03 using a speed of 1.27 millimeters per minute, and wherein the poly(arylene ether) and the polyolefin are present in amounts such that the weight ratio of the poly(arylene ether) to polyolefin is 1.0 to 1.6.
