PROBLEM TO BE SOLVED: To obtain an olefinic thermoplastic elastomer composition excellent in oil resistance, heat resistance, forming property and flexibility. SOLUTION: This olefinic thermoplastic elastomer composition contains (A) 40-90 pt.wt. polypropylene resin having 0.1-5g/10min melt flow rate (ASTM D1238; 230 deg.C under 2.16kg load), (B) 10-60 pt.wt. olefinic copolymer rubber [provided that the total amount of the components (A) and (B) is 100 pts.wt.], and (C) 20-150 pt.wt. softening agent, and is crosslinked so as to become >=97wt.% gel content. |
