Silicone Rubber Gaskets can be purchased in a wide range of shapes and sizes, and also have many different applications. These gaskets are popular in all types of industry and these can include, the engineering industry, the aircraft industry, the structure 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 great seal. In the case of silicone O rings where some motion may be required, lubrication is very often achieved through the fluid being sealed. - Rubber Products Suppliers

As a result of properties of the silicone these gaskets can take on many forms for example;

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

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

Silicone has several useful properties and 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 used to prevent leakage between two surfaces. Gaskets usually require some type of compression, and therefore a point of yield or some kind of de-formation is required by the gasket. Silicone rubber gaskets are fantastic for such applications. An O-ring for instance is an extremely versatile type of silicone gasket, and is commonly used in all types of pipe-work and plumbing applications, and will even allow a modest amount of motion between the two surfaces whilst efficiently sealing them.

Various kinds of silicone gaskets can include;

o Silicone gaskets
o Solid silicone gaskets ( popular on metal closures)
o Sponge silicone gaskets
o Silicone foam gaskets (closely linked to sponge gaskets)
o Injection moulded silicone gaskets

Foam gaskets from the opened cell type can be used as dust seals or shock and vibration gaskets. Closed cell is mainly used for environmental seals. - Rubber Products Suppliers
