THERMOPLASTIC RESIN COMPOSITION

摘要

PURPOSE: Provided is a thermoplastic resin composition excellent in extrusion and calender processability, which can be used for the surface material of interior parts of cars. CONSTITUTION: The thermoplastic resin composition contains: 100pts.wt. of a base composition comprising 5-45wt% of a polypropylene resin, 5-80wt% of an olefin-based copolymer rubber, 5-30wt% of a processing oil, and 1-30wt% of a low density polyethylene resin, a high density polyethylene resin, or a mixture thereof, wherein the polypropylene resin is an atactic polymer produced from a block or random copolymer of propylene and an alpha-olefin monomer; 0.01-5pts.wt. of an organic peroxide-based crosslinking agent; 0.01-5pts.wt. of a crosslinking aid; and 0.5-5pts.wt. of polytetrafluoroethylene.
