RUBBER-COMPOUNDING INGREDIENT COMPOSITION

摘要

PURPOSE:To provide a rubber-compounding ingredient composition capable of easily miscible in the production of a master batch by mixing a rubber chemical master batch with a rubber binder especially when both components have different polarities even if the rubbers are the same or different kinds. CONSTITUTION:The objective rubber-compounding ingredient composition is composed of (A) 70-90wt.% of rubber chemicals, (B) 10-20wt.% of an acrylonitrile-butadiene rubber containing <=20wt.% of bonded acrylonitrile and (C) 5-10wt.% of oils. A composition for rubber can be produced by compounding the rubber-compounding ingredient composition.
