PURPOSE: To manufacture EPDM band-like product, which is excellent in heat resistance, and has favorable sealing performance due to small. permanent compressive strain, by injection molding. CONSTITUTION: In the method for injection molding rubber composition mainly made of ethylene-propylene-based rubber, the ethylenepropylene-based rubber, which contains 30-55wt.% of propylene and has the Mooney viscosity ML1+4 (100 deg.C) of 20-80, is used and, as vulcanizing agent, organic peroxide is added. |
