Abstract
A rubber composition comprising: at least one hydrogenated nitrile rubber, and at least one thermoplastic polyolefin, wherein the weight ratio (hydrogenated nitrile rubber:thermoplastic polyolefin) is in the range from 95:0.5 to 50:50. The composition retains substantially the resistance to heat and chemicals and the mechanical properties characteristic of hydrogenated nitrile rubber upon curing.
Claims13
A rubber composition comprising:
- at least one hydrogenated nitrile rubber,
- at least one thermoplastic polyolefin, and
- a curing system which causes the thermoplastic polyolefin to be at least partially cross-linked upon curing of the hydrogenated nitrile rubber,
- wherein the weight ratio (hydrogenated nitrile rubber:thermoplastic olefin) is in the range from 95:0.5 to 50:50.

A vulcanized rubber composition obtained by vulcanizing a rubber composition comprising:
- at least one hydrogenated nitrile rubber,
- at least one termoplastic polyolefin, and
- a curing system which causes the thermoplastic polyolefin to be at least partially cross-linked upon curing of the hydrogenated nitrile rubber,
