PURPOSE: To obtain a rubber composition, having well balanced physical properties such as strength characteristics, oil, cold and ozone resistances and suitable as various sealing materials, hoses, etc. n CONSTITUTION: A rubber composition is obtained by blending (A) an ethylenic copolymer rubber containing one or more selected from the group consisting of acrylic acid esters and methacrylic acid esters and ethylene as constituent units with (B) a hydrogenated unsaturated nitrile-conjugated diene-based copolymer rubber at (95-5):(5-95), preferably (70-30):(30-70) weight ratio. (C) A vulcanizing agent (e.g. di-tert. butyl peroxide), as necessary, in an amount of 1-10 pts.wt., preferably 2-6 pts.wt., based on 100 pts.wt. total amount of the compositions (A) and (B), is blended. n COPYRIGHT: (C)1992,JPO&Japio |
