Ageing and oil resistance of fiber-reinforced CR/NBR blends

Nitrile rubber (NBR) as an excellent oil resistant was blended with the the rmal resistant poly chloroperene rubber (CR) to obtain rubber product with satisfactory thermal and oil resistance. The effect of curing system and bl end ratios upon the physico-mechanical, swelling and ageing properties were studied for polyester reinforced vulcanizates. The obtained results were c ompared with the grafted and ungarfted viscose fibers.
