High temperature Viton o-ring Viton synthetic rubber containing fluorine atoms, has excellent heat resistance, oxidation resistance, oil resistance and chemical resistance, which is mainly used in aviation, chemical, oil, automotive and other industries department, as the sealing material, anti-media materials and insulating materials. Viton (FPM) is a copolymer of a fluorine-containing monomer from organic elastomer. It features high temperature resistance up to 300 ℃, acid, oil is the best oil and rubber, anti-radiation, good resistance to high vacuum performance; electrical insulation, mechanical properties, chemical resistance, ozone resistance, resistance to atmospheric aging resistance are excellent. Operating temperature range: -40 ℃ ~ + 300 ℃. ※ seal high abrasion resistance, sealing surface wear and tear with automatic elastic compensation. Ring good self-lubricating properties. Can be used for oil-free seal. Simple ring structure, easy installation. Seal Working pressure: 0 to 300MPa; working speed: ≤15m / s. Sealing is to ensure the normal operation of the hydraulic system of the most fundamental and important means. Hydraulic, pneumatic system leaks are most seal failure caused due. Performance and reliability O-ring seals and sealing devices is an important measure of system design and manufacturing quality. If not sealed properly, can cause internal components and systems, external leakage, the system will not only reduce the volume efficiency can not be established in severe pressure leaving the system does not work; leak outside the device will be dirty, polluting the environment. Therefore, the correct use of the O-ring to ensure normal operation of the hydraulic system is very important. 1, the hydraulic system of the seal material requirements and classification 1.1, the hydraulic system of the seal material requirements (1) in the hydraulic oil in better stability, namely small volume change, expansion, shrinkage is small, easy to dissolve , does not cause change in hardness; when the temperature changes in the scope of use, flexibility and hardness change is smaller; (2) has a good seal and a suitable elastic, compression resilience in the hydraulic oil in a large, permanent deformation; (3) good wear resistance, low friction, flexible movement, long working life; simple (4) structure, easy processing, use and maintenance. 1.2, the classification of the seal according to the relative movement between the sealing surface for the seals can be divided into dynamic sealing and static sealing two categories. The most commonly used seal its cross-sectional shape named, have O type, Y type, Yx, V-type and combined seals. O-ring cross section is circular, as various fluid seal oil, water, gas, etc., there is static seal and dynamic seal type 2 Kunshan Hui Yang Sealing Products Co., Ltd.
