Owing to their ability to resist extreme temperatures, and their moisture repelling qualities, silicone rubber gaskets are commonly used in adhesives, sealants, medical applications, cookware, insulation and lubricants.

Silicone rubber is a polymer made from chemical elements including oxygen, hydrogen and silicon.

Some of silicone’s properties include low toxicity, thermal stability, water repelling, resistance to sunlight and oxygen, non-stick and electrical insulation.

Different types of silicone gaskets include solid gaskets, sponge gaskets, foam gaskets and injection moulding gaskets.

Solid silicone rubber gaskets are commonly used on metal closures, whereas silicone sponge gaskets are used from environment seals. Silicone performs extremely well under UV light and is stable over a broad temperature range.

Silicone foam gaskets and seals are similar to silicone sponge. The cell structure, however, is closed, in contrast to sponge, which has an open cell structure.

Open cells are used for dust seals or shock gaskets and closed cells are used for  environmental seals.

Injection moulding silicone gaskets and seals are used to improve sealing in water submersion scenarios.

Using innovative cutting and jointing equipment, Silicone Engineering can produce silicone rubber seals and gaskets in both solid and sponge, punched or water-jet cut from a variety of silicone sheet materials produced on site.
