Silicone Rubber Gaskets



Silicone Rubber Gaskets can be found in a wide range of shapes and sizes, and possess many different applications. These gaskets are widely used in all types of industry that can include, the engineering industry, the aircraft industry, the building industry and the catering industry, to mention just a few. They are very commonly employed between two or more surfaces, where leaks of fluid or air need to be contained. The surfaces are combined and the silicone rubber gasket is compressed which produces a fantastic seal. In the case of silicone O rings where some motion are usually necessary, lubrication is very often achieved through the fluid being sealed. - Gaskets

Due to the properties of the silicone these gaskets may take on many forms such as;

o Mitre cut letter box shape
o Horse shoe shape
o O ring shape

Silicone has very versatile properties because of its ability to resist extreme temperatures, and moisture repelling qualities. It is commonly used in adhesives, sealants, medical applications, cookware, insulation and lubricants. Silicones are polymers which can be made from chemical elements and will include oxygen, hydrogen and silicon.

Silicone has several useful properties plus some of these can include;

o Low toxicity
o Thermal Stability
o Water Repelling
o Good resistance to sunlight and oxygen etc.
o Non-stick
o Good electrical insulation

Silicone gaskets are mechanical seals accustomed to prevent leakage between two surfaces. Gaskets usually require some form of compression, and therefore some degree of yield or some form of de-formation is required by the gasket. Silicone rubber gaskets are fantastic for such applications. An O-ring as an example is an extremely versatile type of silicone gasket, and is commonly employed in all types of pipe-work and plumbing applications, and will even allow a tiny bit of motion between the two surfaces whilst efficiently sealing them.

Different types of silicone gaskets can include;

o Silicone gaskets
o Solid silicone gaskets ( commonly used on metal closures)
o Sponge silicone gaskets
o Silicone foam gaskets (closely related to sponge gaskets)
o Injection moulded silicone gaskets

Foam gaskets of the opened cell type can be used as dust seals or shock and vibration gaskets. Closed cell is primarily used for environmental seals. - Gaskets
