What is the difference between asbestos and non-asbestos board sealing materials

Asbestos and non-asbestos sealing materials, asbestos sealing materials are more resistant to high temperature than non-asbestos sealing materials. The main components of asbestos sealing materials are asbestos, filler and rubber, during which the temperature resistance of asbestos and filler is very high; Most asbestos-free sealing materials are mainly composed of mineral fiber, organic fiber, filler and rubber. During this period, the temperature resistance of organic fiber is usually at 200 ℃, and the current temperature resistance of asbestos gasket has reached 1000 ℃.
