ABSTRACT:
The present invention is directed to improved processes for making plastic articles, and articles made therefrom. In a broad aspect, the invention is directed to improved processes and articles made therefrom, that include the steps of providing as separate materials a first material that includes a thermoplastic polyolefin, a second material including an admixture of a particulated filler and a second thermoplastic polyolefin, and a third material that includes an elastomer; applying a shear force to the first, second and third materials, while the materials are at an elevated temperature for blending the materials to form a molten blend; shaping the molten blend and solidifying the molten blend.
