Abstract
PURPOSE: To prepare the titled rubber composition having balanced various strengths and rubber characteristics, and capable of forming a vulcanizate having extremely high heat aging characteristics, by compounding an ethylene/α-olefin/ polyene rubber and ethylene/propylene copolymer rubber.
CONSTITUTION: The titled composition is prepared by compounding (A) 100pts.wt. of an olefin rubber mixture consisting of (a) 55W90pts.wt., pref. 60W80pts.wt. of an ethylene/(4W10C α-olefin)/polyene copolymer rubber (pref. having an iodine value of 4W30) wherein the molar ratio of ethylene/α-olefin is 80/20W95/5 and (b) 45W10pts.wt., pref. 40W20pts.wt. of an ethylene/propylene copolymer rubber wherein the molar ratio of ethylene/propylene is 50/50W85/15, with (B) ≥0.003pt. mol of an organic peroxide vulcanizing agent, (C) ≥0.003pt.mol of a vulcanization assistant such as a quinone dioxime compound, and (D) ≥0.5pt.wt. of an antioxidant such as a phenolic compound.
USE: Insulation layer of a high-voltage power transmission cable, parts near the automobile engine, etc.
