Details : Silicone rubber mat has higher heat resistance and chemical stability that help it in providing better electrical insulation. It has high elasticity and compressibility as well as excellent resistance to cold temperatures. Silicone rubber mat has resistance to wide temperature range. It offers excellent resistance to extreme temperatures, the range of which can be from minus 100°F to plus 500°F. This rubber can be used indefinitely at 150°C that doesn't lead to any change in the properties of silicone rubber. It can withstand the temperature of 200°C for 10,000 hours or more. Some of the silicone rubbers can even withstand heat of 350°C for short periods. Silicone rubber has outstanding oil resistance at high temperatures. From among other common types of synthetic rubbers, nitrile rubber and chloroprene rubber have somewhat higher oil resistance at temperatures lower than 100°C but at higher temperatures, silicone rubber is superior to all other rubber types. Silicone rubber has exceptional weather resistance. Ozone created by corona discharge does not deteriorate silicone rubber. Thus, silicone rubber can be exposed to wind, rain and UV rays for longer periods without any change in its physical properties. The tensile strength, tear strength, elongation and compression set of silicone rubber are far superior to conventional rubbers. The tear strength of silicone rubber is usually around 9.8 kN/m. certain high-strength types of silicone rubbers also come with tear strength between 29.4 kN/m and 49.0 kN/m, achieved through polymer modification and/or judicious selection of fillers and cross linkers. Thermal conductivity of silicone rubber is higher than most of the other rubbers. Silicone rubber with high thermal conductivity is used to make products like thermal interface sheets and heating rollers. Silicone rubber has excellent moisture and steam resistance. It can be immersed in cold, warm or boiling water for longer periods with water absorption of about 1%. This doesn't affect its mechanical strength or electrical properties. When it comes in contact with steam under ordinary pressure, there is no deterioration of silicone rubber. However, high pressure steam at temperatures above 150°C can cause breakdown of the siloxane polymer and a decline in the properties of the rubber. It is metal detectable. It glows in the dark. Silicone rubber is also electrically conductive. Apart from being resistant to oil, silicone rubber is also resistant to chemical, acid and gas. Silicone rubber is flame retardant and has the property of low smoke emission.
