Silicone Rubber Sheet
Silicone offers many advantages over other forms of elastomers. It is well known for its use in food, pharmaceutical and other clean industry applications. It is a resilient material capable of maintaining many of its properties at extremely low and high temperatures.
Some grades of silicone rubber can remain flexible, and show low levels of compression set, down to temperatures as low as -100 °C and as high as 315 °C. It is naturally electrically insulating but can be compounded to offer high resistance for the bleeding of static charges or to offer a low resistance to conduct signal voltages. High tear resistance, good elongation at break and tensile strength are some of the other characteristics of silicone
Silicone will keep constant even at high temperatures, but should not be used with high pressure steam. Silicone has excellent resistance to heat (dry air), at +200°C intermittent and will remain flexible at low temperatures of -70°C and is also resistant to ultra-violet light, Ozone, sea water and weathering. Silicone also exhibits low in flammability and low smoke toxicity.
Silicone solid rubber sheets are available in 1.2 metres width and can be bought as individual 1 metre lengths or multiples of 1m and are available in 10m or 5m rolls depending on the thickness. Colours include: translucent (opaque), white, red oxide as standard and blue, grey and black are readily available. The thickness range are between 0.3mm and 12mm, although other thicknesses can be supplied on request. The standard hardness is 60° shore and we can offer hardness from 30° to 80° in some instances.ings have excellent resistance to extreme temperatures, -10°C to +260°C. Some special compounds can operate beyond 316°C.
