Abstract
A soft thermoplastic, elastomeric alloy containing a thermoplastic, elastomeric block copolymer material, a polyethylene, and a polyphenylene ether material, prepared by blending in an extruder with an L/D ratio equal to or greater than 30 to 1. The alloy comprises a blend of from about 80 to 98% thermoplastic, elastomeric block copolymer material; from about 1 to 10% by weight of low melt index, highly crystalline polyethylene; and from about 1 to 10% by weight of polyphenylene ether. The material demonstrates excellent creep resistance at elevated temperatures as well as a variety of other excellent physical properties.
