ABSTRACT OF THE DISCLOSURE The present invention provides a thermoplastic mat- erial for use under conditions demanding high strength at elev- ated 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 polyure- thane 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 con- ventional 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°F at 66 psi and 300°F at 264 psi) and high tensile and flexural strengths.
