Heat resistant gaskets are widely used in various high-temperature working environments, such as engines, boilers, pipelines, etc. In these situations, gaskets need to withstand the erosion of high temperature, high pressure, and corrosive media, so the performance of heat-resistant gaskets is crucial.

Rubber gaskets have various materials, including common ones such as nitrile rubber, chloroprene rubber, fluororubber, silicone rubber, etc. Different rubber materials have different performance characteristics, and suitable materials can be selected according to specific usage environments. For example, silicone rubber has outstanding high and low temperature resistance, maintains good elasticity in the temperature range of -70 ℃ to+260 ℃, is resistant to ozone and weather aging, and is suitable as a sealing gasket in thermal machinery.
