Heat resistant rubber gasket

All rubber materials are heat resistant to some extent, so it is possible to find heat resistant rubber gasket made of virtually all materials belonging to rubber materials. However, what decides which material you will opt for when ordering a heat resistant rubber gasket is the heat to which the gasket will be exposed.

The two materials stand out in terms of the temperature they can withstand, while the rubber gasket remains unchanged, as well as its function. These materials are silicone and Wheaton. Silicone of all can withstand the largest temperature range, from almost minus 100 degrees Celsius and also over 250 degrees Celsius. That is why silicone is the best choice if the gasket will be exposed to both high and low temperatures. Viton on the other hand should not be exposed to temperatures below minus 50 degrees Celsius, but can be found in an environment where it is over 300 degrees Celsius, which is even more than silicone and that is why Viton rubber gasket roads. Other materials like Neoprene, Ethylene Propylene Diene Monomer (EPDM), Nitrile and others do not have poor resistance to high temperatures, because they can all be exposed to temperatures of over 100 degrees Celsius, but they cannot be exposed to extreme temperatures, such as 300 degrees. The cold limit they can withstand is also around minus 50.

Whether you use a rubber gasket as a mechanical seal, to protect two surfaces that touch, or for some third reason, it is essential that the size is 100% appropriate, otherwise you will not achieve what you want. You can order a custom rubber gasket from us, which includes a choice of materials and sizes, as well as colors. If you’re wondering why color would matter, a custom color is chosen to make it easier to label rubber gaskets for different purposes.
