Abstract
PURPOSE: A composition having improved water tree resistance, good flexibility, and small deformation at high temperature, obtained by adding an inorganic filler and an inorganic stabilizer to a specific ethylene-α-olefin-polyene terpolymer rubber, crosslinking it with an organic peroxide.
CONSTITUTION: Ethylene is polymerized with 4W10C α-olefin and polyene in such a way that a polymerization molar ratio of ethylene/α-olefin is (80/20)W (95/5) and the amount of the polyene component is 4W30 calculated as an iodine value, to give ethylene-α-olefin rubber, which is blended with 5W60PHR inorganic filler selected from calcined clay, magnesium carbonate, and barium sulfate and 2W30PHR inorganic stabilizer, and crosslinked with an organic peroxide. Zinc oxide, lead oxide, etc. may be used as the inorganic stabilizer, and a crosslinking auxiliary such as sulfur, etc. may be preferably used together with the crosslinking agent. An antioxidant such as 2-mercaptoimidazole, etc. is effectively used with them.
