General Features of Silicone Rubber

The features of synthetic rubber can differ depending on the polymer. Natural rubber, EPDM, Neoprene, Nitrile and Viton® all have distinctive properties that make them ideal for specific applications.

Silicone is a polymer that is used to create synthetic rubber. While it has a wide range of grades and variants, every sheeting alternative has general properties in common.

Resistance to Many Factors

With a multitude of unique characteristics, silicone rubber can be used for a variety of applications including the manufacture of electrical, chemical, industrial and automotive components. It also has excellent resistance to different factors, such as:

Heat and Cold

Silicone rubber can withstand temperatures down to -60°C – quite impressive when compared with organic rubber, which can accommodate temperatures between -20°C and -30°C. Additionally, it remains tough even after exposure to temperatures of up to +200°C.

Moisture and Steam

With the ability to tolerate excessive moisture and steam, this synthetic polymer doesn’t deteriorate when in direct contact with water for prolonged periods.


Silicone rubber can also stand up to the elements such as ozone, wind, rain and ultraviolet light. This makes it ideal for outdoor applications like window seals, door profiles and garden hoses, etc.

Oils, Solvents and Other Chemicals

With exemplary resistance to oil at high temperatures, silicone rubber will maintain its efficiency even after extensive exposure to polar organic compounds, dilute acids or bases.

Electrical Insulation

Known for its reliably high insulating properties, it is applicable for use in the electrical industry and other industrial sectors where there is constant exposure to an electric current.

Compression Set

Silicone rubber remains unaffected by compression deformation, even when exposed to a temperature range of -60°C up to +200°C. This characteristic makes silicone rubber a suitable material for the manufacture of rubber gaskets for specific industries.

Ability to Withstand Wear and Tear

With a tensile strength of 6.0 to 7.5 Mpa and a tear strength of around 9.8kN/M, silicone rubber is surely the perfect material to use in moulding and other fabrication processes that require high tensile and tear resistance.

Applicable for Food Contact

Tested silicone rubber (accredited and approved by quality standards) can be rated for food contact – which can be safe for applications in areas that involve food and beverages.

Whatever the application, make sure that you only choose high quality silicone sheeting to achieve maximum benefits. Coruba manufactures silicone products that are REACH, RoHS, PAH and CE compliant – ensuring a quality product that doesn’t compromise your safety! We also have a wide selection of silicone rubber sheeting that complies with US FDA 21 CFR177.2600 & SGS. Phone us on 01702 560194 for more product details.
