Silicone Rubber Gaskets


Silicone rubber gaskets are high-performance Sealing Rings with an extraordinary resistance to extreme temperatures.  Silicone gaskets are used to prevent leaks between different substrate sections in a wide range of applications.  At Kemtron Gaskets and Seals we have the facilities to manufacture standard gasket and washer sizes, as well as bespoke parts in-house, each of which are produced from the highest quality silicone gasket material.  Please visit our Resources section to access the data sheets to get information on the silicone rubber gasket properties and material specifications.

Product Description

Silicone rubber gaskets have an excellent temperature resistance in both hot and cold environments.  They also have exceptional UV and ozone properties which makes them suitable for outdoor applications.  Being an inert material, silicone generally does not react to the majority of chemicals, which means that it is popular for use in medical and industrial applications.

Silicone Gasket Temperature

Gaskets in silicone material are extremely resilient and can uphold a lot of their properties at very high and low temperatures.  The low temperature properties of a silicone gasket are unmatched by any other elastomer.  In addition, our silicone rubber gaskets can remain flexible at temperatures between -100°C to +230°C.  This makes our gasket material the ideal material for applications exposed to such extreme temperatures.

If you have a specialist gasket requirement, then Kemtron Gaskets and Seals is the one for you.  Our industry experts are available to answer any questions you may have about silicone gasket uses and silicone gasket temperature capabilities.
