The 61000 series comprises closed-cell sponge silicone products, available in a variety of densities.

Silicone is a synthetic inorganic elastomer that is highly stable in environmentally challenging conditions. It can maintain its performance characteristics for long periods of time. Silicone properties have significantly less variance than other polymers when significant changes are observed in conditions and operating temperatures.

Silicone’s resistance to extreme temperatures constitutes this material’s most beneficial feature. Silicone performs extremely well at service temperatures as high as 600°F and as low as -150°F. When used at 250°F, silicone’s useful life can last as long as 20 years. With such great longevity at high temperatures, silicone’s useful life is almost unlimited under normal conditions.

At temperatures ranging from -150°F to 500°F, the compression set of silicone is inferior to that of most elastomers.

Silicone offers very good resistance to sunlight, ozone and weather. The physical properties of silicone will not be impaired when the material is put in an environment where there is moisture. It will not grow mould, and, conversely, it will not parch in very dry environments.

Low thermal conductivity and excellent insulation features are some of the characteristics of silicone. Being a neutral material, silicone will induce neither corrosion nor deterioration in other materials it may be in contact with.

Some compounds in our 61000 series have very good flame resistance. They meet a number of flammability standards, including UL 94-V0 and ASTM E162.
