PURPOSE: Provided is a thermoplastic styrene/butadiene/styrene composition for producing car mats by a calendering process, which is excellent in flexibility, smoothness, processability, and productivity. CONSTITUTION: The thermoplastic styrene/butadiene/styrene composition contains: 30-80wt% of a thermoplastic styrene/butadiene/styrene polymer having a weight average molecular weight of 100,000-150,000 and a glass transition temperature of -90 to 90deg.C; 10-30wt% of a polyolefin having a density of 0.8-1.0g/cm¬3, a weight average molecular weight of 220,000-700,000, a glass transition temperature of -10 to 10deg.C, and a melting temperature of 145-160deg.C; and 10-50wt% of an inorganic filler such as calcium carbonate, mica, talc, or a mixture thereof. |
