Rubber Neoprene Gasket for Oil Sealing

Neoprene Gasket & Neoprene Washers

Neoprene Gasket & Seal, also called Neoprene Washers, Neoprene Sheet, CR Seal & CR Gasket, which mainly made by rubber compression mold tooling for Oil Sealing Gasket.

Neoprene Gasket have good physical properties, oil proof, heat & flame resistance, sunlight resistance, ozone resistance, acid & alkali resistance and anti chemical. However, not good cold tolerance and storage stability.
Neoprene Washer have a good tensile strength, elongation crystalline and adhesion.

Neoprene Seal, are excellent about aging resistance, heat & oil resistance and chemical resistance

Neoprene Gaskets, which weather resistance, ozone resistance and aging resistance, is rank only second to EPR Gasket and II R ( Isobutylene Isoprene Rubber )
Oil resistance ranks only second to that of NBR.
Heat resistance is equal to that of NBR materials.
Neoprene Gasket decomposing temperature is 230～260℃, working in 120～150℃ for a short period and 80～100℃ for a long time, with a certain flame resistance.  Inorganic acid and alkali resistance is good. Cold tolerance and insulation are poor.

Rubber CR Gasket bad storage stability, easily appearing self-vulcanization phenomenon and it tend to harden as Mooney Viscosity increases.
