A process and resulting thermoplastic article is provided suitable for use in constructing furniture. The thermoplastic article contains hardened particulates such as powders of alumina oxide or ceramic microspheres which bring about an improved cut and scratch resistance to the surface of the articles. The hardened particulates may be integrally mixed with the extruded product or applied post-molding to a surface of the shaped article. In addition, spherical additives may be included in the extrusion polymer which reduces shear forces and provides an improved wood grain appearance in the extruded article.
