Silicone seals are generally resistant to high temperatures, with their heat resistance primarily determined by factors such as the type and formulation of silicone. Here is a detailed analysis:  Under normal circumstances, standard silicone seals can typically operate continuously at temperatures ranging from 150°C to 200°C. Within this temperature range, silicone seals maintain good elasticity, flexibility, and sealing performance, minimizing issues like deformation, hardening, or brittleness, thereby effectively fulfilling their sealing function.Special Cases: Silicone seals treated with special formulations and processes exhibit superior high-temperature resistance, capable of short-term operation at temperatures up to 250°C or even higher. For instance, in specialized fields such as aerospace and high-end electronics, these high-performance silicone seals are employed to meet sealing requirements in extreme environments.However, when the temperature exceeds the tolerance range of the silicone sealing ring, its performance will degrade, leading to issues such as accelerated aging, loss of elasticity, and reduced sealing effectiveness.
