Silicone rings are a type of sealing ring. Silicone is a rubber material that, thanks to its unique properties—wide temperature resistance and excellent chemical stability—is often compared to fluororubber. They are collectively referred to as specialty rubbers. Silicone rubber is widely used in the manufacture of various sealing components. 。
Advantages of silicone sealing rings:
Heat Resistance: Silicone rubber exhibits significantly superior heat resistance compared to conventional rubbers. It can be used continuously at 150°C for virtually indefinite periods without any loss of performance, withstands continuous operation at 200°C for up to 10,000 hours, and remains serviceable at 350°C for a limited duration. It is widely employed in applications demanding high-temperature resistance, such as sealing rings for thermos flasks and heat‑resistant handles for pressure cookers.
Cold resistance: While ordinary rubber begins to lose its elasticity at around –20° to –30°, silicone rubber retains good elasticity even at –60° to –70°. Certain specially formulated silicone rubbers can withstand extremely low temperatures, such as in low‑temperature sealing rings.
