| 摘要 |
This invention provides a plasticized hydrogenated nitrile composition. The composition of the present invention must contain a peroxide vulcanization system and a specific type of plasticizer. Vulcanizates according to the invention have superior resistance to hot air ageing in comparison to conventionally plasticized compositions, and most surprisingly, in comparison to non-plasticized compositions. The compositions of the present invention may be used to prepare hoses, seals, gaskets and other rubber goods.
