Classification specification for asbestos mats
High pressure asbestos gasket (G2181): mainly used for steam, hydraulic, gas, oil and non corrosive media seal.Oil resistant asbestos gasket (G2184): mainly used for steam, hydraulic, gas, oil, solvent and non corrosive media seal.Asbestos rubber gasket refers to asbestos and rubber composite gasket products, used in liquid sealed environment. Asbestos rubber gasket manufacturing, in addition to asbestos fiber and rubber, added with agent and filler material, through the processes of mixing, hot roll forming and vulcanization made with good sealing performance.
Applicable to water, water vapor, oil, solvents, medium acid and alkali seal, asbestos gasket is mainly used in the middle and low pressure flange connection seal.Low pressure asbestos gasket (G2183): low pressure asbestos gasket is made of a white asbestos fiber, suitable for the majority of low demand, asbestos gasket is mainly used for steam, water, gas, oil seal and non erosive medium.Medium pressure asbestos gasket (G2182): mainly used for steam, hydraulic, gas, oil and non corrosive media seal.
Asbestos fiber, rubber as the main raw material, and then with rubber compounding agent and filling material, through mixing, stirring, hot roll forming, vulcanization and other processes made. Asbestos rubber gasket according to its formula, process performance and use of different, can be divided into ordinary asbestos rubber gasket and oil resistant asbestos rubber gasket. Depending on the temperature and pressure used, it can be divided into low pressure asbestos rubber gasket, medium pressure asbestos rubber gasket and high pressure asbestos rubber gasket.
