ACRYLONITRILE-BUTADIENE RUBBER COMPOSITION FOR OIL SEALING

摘要

PURPOSE: Provided is an acrylonitrile-butadiene rubber composition for oil sealing which has high strength, high elongation rate and high tensile strength despite using small amount of filler. CONSTITUTION: The composition comprises: 100wt.% of acrylonitrile-butadiene rubber; 10-75wt.% of carbon black; 5-10wt.% of clay particle with particle size of 100nm or less which is a layered clay mineral treated with emulsifier; and 0.1-1wt.% of cross-linking agent.
