  • Silicone rubber, a synthetic elastomer, is derived from the combination of silicon, oxygen, carbon, and hydrogen. It possesses exceptional heat resistance, operating effectively in temperatures ranging from -100°C to 300°C (-148°F to 572°F), making it suitable for both high-temperature and low-temperature environments. This inherent thermal stability is one of the primary reasons why silicone rubber gasket sheets are favored over other materials.
