PURPOSE: A sheet composition for the interior of vehicles is provided to have excellent physical strength, oil resistance, and cyclic fatigue properties, and to improve the productivity of a sheet without an additional surface treatment. CONSTITUTION: A sheet composition for the interior of vehicles comprises a urethane based thermoplastic elastomer and a styrene based thermoplastic elastomer with a weight ratio of 10-30 : 70-90. The urethane based TPE has a viscosity of 1.11-1.28 and a hardness(Shore A) of 75-99. The styrene based TPE is a saturated rubber type block copolymer, which is one or more kinds selected from the group consisting of SEBS(styrene-ethylene/butylene-styrene), SEPS(styrene-ethylene/propylene-styrene), SEBC(styrene-ethylene/butylene-ethylene block copolymer), and HSBR(hydrogenated styrene butadiene rubber). |
