<P>PROBLEM TO BE SOLVED: To provide a gasket having superior sliding property and stress relaxing property and good flow rising property and pulsation property. <P>SOLUTION: A resin composition contains a component (C): 1 to 45 wt.% of a polyolefin resin with respect to total 100 wt.% of a component (A): 25 to 90 wt.% of a block copolymer and/or a hydrogenated block copolymer having a polymer block P mainly composed of a vinyl aromatic compound and a polymer block Q mainly composed of conjugated diene; and a component (B): 10 to 75 wt.% of hydrocarbon rubber softener. The gasket is obtained by forming the above resin composition and has at least one or more peaks and/or peak shoulders within the range of molecular weights of 250,000 to 350,000 and 100,000 to 150,000. <P>COPYRIGHT: (C)2013,JPO&INPIT |
