Abstract
A highly filled, extruded thermoplastic material which has a smooth, uniform speckled surface without any secondary finishing operations. The thermoplastic material contains a polyalkylene terephthalate resin, a polycarbonate resin, a large quantity of a filler material, a stabilizer for the resin materials and a sufficient quantity of a non-dispersing pigment to give the extruded thermoplastic material a speckled surface appearance.
