Sealing ring

Advantages: good resistance to oil, water, solvent and high pressure oil. Good compression distortion, abrasion resistance and elongation.

• good oil resistance, non-polar and weak polar oils basically no swelling

• superior to natural, butadiene and other general purpose rubber.

• good abrasion resistance, its abrasion resistance is 30%-45% higher than natural rubber

Disadvantages: not suitable for polar solvents, such as ketones, ozone, nitrohydrocarbons, MEK and chloroform

• poor elasticity, cold resistance, flexural flexibility, tear resistance, high deformation heat generation

• poor electrical insulation performance, belongs to semiconductor rubber, not suitable for electrical insulation materials

• poor machining performance

Operating temperature: the general operating temperature range is -25~100 ℃

Nitrile butadiene rubber (NBR) is a highly saturated elastomer obtained by special hydrogenation of NBR. Hydrogenated nitrile butadiene rubber has good oil resistance (good resistance to fuel oil, lubricating oil and aromatic solvent). And because of its highly saturated structure, it has good heat resistance (-60 to 180 degrees), excellent chemical corrosion resistance (good resistance to freon, acid, alkali), excellent ozone resistance, high compression resistance permanent deformation performance; At the same time, hydrogenated nitrile butadiene rubber also has the characteristics of high strength, high tear performance and excellent abrasion resistance.
