List several common gaskets

Sealing gasket is a kind of material used in machinery, equipment, pipelines, etc., for sealing. Common sealing gaskets are as follows:

High and medium pressure asbestos rubber sheet gasket: Asbestos rubber gasket is made of asbestos fiber and rubber as the main raw materials, supplemented by rubber compounding agents and fillers, through mixing and stirring, hot roll forming, vulcanization and other processes.

Oil-resistant asbestos rubber gasket: refined from high-quality asbestos fibers, oil-resistant fibers, fillers, colorants, etc., widely used in pipelines and equipment in the petroleum and chemical industries, and the corresponding grade model can be selected according to the working conditions . Oil-resistant asbestos gaskets are mainly used for the sealing of steam, hydraulic, gas, oil solvents and non-corrosive media.

Sealing gasket: a sealing product made of aramid fiber with high strength and high abrasion as the main material and special material with good lubricity. This sealing product has excellent lubricity and wear resistance. It can show its outstanding features on liquid devices that mix solid and liquid phases.

Non-asbestos sheet gasket: It is a sealing material made of aramid and other organic fibers and plant fibers, nitrile rubber, and inorganic minerals at high temperature. Because it contains few asbestos fibers, it is suitable for asbestos gaskets. Alternative products for non-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-permeability. It is a good environmentally friendly material to replace asbestos gaskets under high temperature and high pressure.

Asbestos pad: It is molded with asbestos cloth and other auxiliary materials, and is used for corrosive high-pressure and high-temperature sealing. Used in reaction kettles, reaction tanks, manholes, hand holes, etc. Operating temperature: -100℃+1000℃; Operating pressure: PN<6.0Mp;

Rubber pad: a kind of vinylidene fluoride and non-fluorine, propylene fluoride, propylene material copolymer colloidal elastomer, widely used in the defense industry and civil industry, its characteristics are: high temperature resistance, ozone resistance, natural aging resistance, resistance Good vacuum, fuel oil resistance, lubricating oil resistance, strong oxidant resistance, chemical resistance and electrical insulation performance.

PTFE lining rubber gasket: PTFE lining rubber gasket is a tetrafluoroethylene sandwich rubber compound gasket. With strong anti-corrosion performance and high sealing resilience, it is suitable for anti-corrosion sealing of low-pressure chemical equipment such as enamel and glass pipelines.
