High, medium and low pressure asbestos rubber sheet gaskets Asbestos rubber gaskets are made of asbestos fiber and sealing ring rubber as the main raw materials, supplemented by rubber compounding agents and fillers, and are made through mixing, hot roll forming, and vulcanization. Asbestos rubber gaskets can be divided into ordinary asbestos rubber gaskets and oil-resistant asbestos rubber gaskets according to their formulas, technological properties and uses. According to the temperature and pressure used, it can be divided into low pressure asbestos rubber gaskets, medium pressure asbestos rubber gaskets and high pressure asbestos rubber gaskets. It is suitable for the sealing of water, water vapor, oil, solvent, medium acid and alkali. Asbestos gaskets are mainly used in the sealing of medium and low pressure flange connections. Oil-resistant asbestos rubber gasket performance characteristics: oil-resistant asbestos rubber gasket is refined from high-quality asbestos fiber, oil-resistant fiber, filler, colorant, etc. It is widely used in pipelines and equipment in the petroleum and chemical industries, and can be selected according to working conditions. model of the corresponding grade. Scope of application: Oil-resistant asbestos gasket: mainly used for sealing of steam, water, gas, oil solvent and non-aggressive medium. Cylinder Gaskets Performance characteristics: Cylinder gaskets are refined from high-quality asbestos fibers, oil-resistant fibers for sealing rings, fillers, colorants, etc., and are widely used in automobile and motorcycle engine cylinders, and models of corresponding grades can be selected according to working conditions. Aramid gaskets Performance characteristics: Aramid gaskets are widely used in the sealing of pumps, valves, pipes, containers, etc. used in fluid conveying equipment for steam, organic solvents, acids, alkalis, etc. Composition and characteristics: It is a sealing product made of aramid fiber with high strength and high grinding capacity as the main material and special material with good lubricity. This sealing product has excellent lubricity and wear resistance. It can display its outstanding features on liquid devices where solid and liquid phases are mixed. Non-asbestos gaskets Non-asbestos gaskets (non-asbestos gaskets) are sealing materials made of aramid and other organic fibers and plant fibers, nitrile rubber, and inorganic minerals that are rolled at high temperature. Since there are few asbestos fibers, Asbestos-free gasket replacement for asbestos gaskets. Non-asbestos gaskets (non-asbestos gaskets) not only have high strength, but also have good resilience, and at the same time have super anti-penetration performance, which is a good environmental protection material to replace asbestos gaskets under high temperature and high pressure. Asbestos pad is molded with asbestos cloth and other auxiliary materials, which is used for corrosive high pressure and high temperature sealing. Used in reaction kettles, reaction tanks, manholes, hand holes and other parts. Use temperature: -100℃—+1000℃; Working pressure: PN<5.0Mp; Rubber pad is a kind of vinylidene fluoride and non-fluorine, propylene fluoride, propylene material copolymerized colloidal elastomer, widely used in national defense industry and civil industry, its characteristics are: high temperature resistance, ozone resistance, natural aging resistance, vacuum resistance , Fuel oil resistance, lubricating oil resistance, strong oxidant resistance, chemical resistance and good electrical insulation properties. PTFE-lined rubber gasket The PTFE-lined rubber gasket is a PTFE-lined rubber composite gasket. It has strong anti-corrosion performance and high sealing resilience, and is suitable for anti-corrosion sealing of low-pressure chemical equipment such as enamel and glass pipes. Non-asbestos gaskets Non-asbestos gaskets are roughly divided into non-asbestos rubber sheet gaskets and non-asbestos copy sheet gaskets according to their formulations, technological properties and uses. They are all made of aramid and other organic fibers and plant fibers, tin Asbestos-free gasket series made of green rubber and minerals through rolling or copying process, because the non-asbestos gasket series not only has high strength, but also has good resilience, and also has super strong Impermeable properties, so they are an excellent environmentally friendly gasket replacement for asbestos gaskets in the automotive and industrial machinery fields.
