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 unlimited 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 extended durations. 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.
