Most seals are wearing parts, should ensure interchangeability, standardization and serialization. Silicone rubber has outstanding resistance to high temperature, ozone and weather aging resistant performance, -70 ~ 260 ℃ operating temperature range can be used to maintain its unique flexibility and resistance to ozone, weather resistance etc., suitable for production of hot bodies in the gaskets required, such as strong light shade sealing gasket ring, valve pad. Since silicone rubber is not oil, low mechanical strength, expensive, oil production is not appropriate sealing products. |
