CROSS-LINKABLE NITRILE RUBBER COMPOSITION AND CROSS-LINKED RUBBER PRODUCT

摘要

A cross-linkable nitrile rubber composition comprising a highly saturated nitrile rubber (A) with a Mooney viscosity (ML 1+4 , 100°C) of 50 or less and an iodine value of 120 or less, an unsaturated carboxylic acid metal salt (B), and an organic peroxide cross-linking agent (C) is provided. A cross-linkable nitrile rubber composition excellent in scorch stability and able to give cross-linked rubber excellent in normal physical properties and bending fatigue resistance can be provided.
