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.

Polymax silicone solid 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. Please ring an advisor to check if unsure.

Silicone sheeting has no resistance to oils. For oil resistance sheeting please see our ARIA rubber sheeting.

Polymax also offer in Solid sheeting:

  • Cutting and fabrication service. Gaskets, seals and strip.

  • Moulded sheet for smaller applications. Colour and hardness variations in small quantity catered for in moulded sheet from 12"x12", shore hardness range 30° to 80°

  • Adhesive backing: Cut sheet and gaskets can be supplied with a pressure sensitive adhesive.

  • Colour matching service. If you wish to colour match to silicone sheeting, we offer a service to nearest RAL/ PANTONE colour chart or to sample swatches. Please ask for more information if required.
