ABSTRACT:
The present invention provides a thermoplastic material for use under conditions demanding high strength at elevated temperatures, e.g., for under-the-hood automotive or truck components.
The material is essentially a three-component alloy of a homopolymer polyamide, a copolymer polyamide, and polyurethane reinforced with a relatively small amount of glass fibers and containing normal amounts of heat stabilizers, ultraviolet screen materials, etc. The material can be formed by any conventional forming method, e.g., by extrusion, injection molding, blow molding, vacuum forming, and the like. Finished articles made from the material are characterized by elevated deflection temperatures (400.degree. F at 66 psi and 300.degree. F at 264 psi) and high tensile and flexural strengths.
