PAINTABLE MOLDABLE ELASTOMERIC THERMOPLASTICS

摘要

Unvulcanized elastomeric thermoplastic composition of a highly crystalline polyolefin, such as polypropylene, and a noncrystalline or semicrystalline polyolefin, such as EPR or EPDM are found to have superior physical as properties well as better processing properties by blending with said composition:(a) a plasicizer such as hydrocarbon oil; or (b) a carbon black with high reinforcing capacity and low aggregate structure such as an HAF-LS black; or(c) both the plasticizer of (a) and the black of (b). The composition are useful for molded and extruded articles such as injection molded automotive decorative and structural parts.
