Rubber seals commonlyRubber seals commonly used materials are as follows:

Rubber is one of the most common materials rubber seals.

? nitrile rubber rubber seals: oil, heat and wear resistance. Widely used in the production of seal products, but not for phosphate series of hydraulic and gear oils containing polar additives. -40 ~ 120 ?, for the production of "O" rings, seals, suitable for general hydraulic and pneumatic systems. Nitrile rubber (temperature 30-85) for petroleum products, air with oil vapors, vegetable and mineral oils; not applicable to exceed 65 ? hot water over 60 ? or hot dry air. Therefore, oil seal products and the use of nitrile rubber based. Nitrile rubber has excellent resistance to fuel and aromatic solvents such as performance, but intolerance ketones, esters and hydrogen chloride and other media.

? HNBR rubber seals: high strength, oil resistance, wear resistance, heat aging resistance. -40 ~ 150 ?, for high-temperature, high-speed reciprocating seals and rotary seals.

? silicone rubber seals: heat, cold is good. A small compression set, but low mechanical strength, -60 ~ 230 ?. Silicone rubber (temperature 70-260) suitable for potable water, hot water, oil-free air and high-temperature steam, which does not apply to oil media. Silicone rubber seals have outstanding resistance to high temperature, ozone and weather aging performance, operating temperature range of -70 ~ 260 ? can maintain its unique using elasticity and resistance to ozone, weather, etc., suitable for production of heat bodies required gaskets, such as strong light shade sealing bushing, valve pad. Since silicone rubber is not oil, low mechanical strength and expensive, it is not appropriate for production of oil seal products. Suitable for high speed rotating mechanical seal and seal food at low temperatures. used materials are as follows:
