Abstract
Filled crystalline thermoplastic resin chips are incorporated into a filled synthetic resin matrix for producing varicolored mineral appearing articles. Wollastonite filled polyphthalamide resin chips increase the surface hardness and decrease the ASTM E 84 Smoke Index of neopentyl glycol/isophthalic polyester molded articles. Crystalline thermoplastics can be extruded in shapes for providing varishaped chips.
