Silicone Rubber Sponge Sheet SIL 16



Cellular silicone rubber is suitable where a soft, easily deformed rubber is required, forexample, for high temperature seals and gaskets. The sheets and punched parts are all available with self-adhesive backing to ease assembly.

Thermal properties

The range is suitable for continuous use at temperatures up to +200ºC. It has even been found that at temperatures as high as +300ºC useful lives of up to 10 hours can be achieved. They are also suitable for use at temperatures as low as -60ºC. 

Chemical composition

This range of polydimethylsiloxane have been “free-blown” with a chemical blowing agent and crosslinked with an organic peroxide. The cellular structure is produced without the use of CFC’s thus making less damaging to the environment. 

Flammability characteristics

Has a Limiting Oxygen Index (LOI) of 28%, the other products have an LOI of 23.2% (BS2782 Part 1) and comply with the following flammability specifications:

FAR 25.853 (a)(1)(iv) and (a)(1)(v) horizontal flammability tests.CAA specification 8 issue 2 (2.2)(c) and (d) horizontal flammability tests. 

Moisture absorption

The range has a very low degree of moisture absorption. Mechanical properties shows little change even after long periods of immersion. 


The product range is available in off-white as standard. Other colours, such as red oxide, are available, we can colour match to most customer requirements. 

Environmental resistance

Silicone rubber has excellent resistance to ozone, oxidation, ultraviolet light, coronadis charge, cosmic radiation, ionising radiation and weathering in general. Typical radiation resistance is greater than 10 grays (greater than 10 rads).
