Nitrile rubber compound
Excellent oil resistance, high wear resistance, good heat resistance, strong adhesion. Its disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance, and slightly low elasticity. Nitrile rubber is mainly used to make oil-resistant rubber products.
