High Temperature Silicone Gasket​ for Oven Demanding applications

Many demanding products and projects require operation in extremely high-temperature environments. Ordinary elastic rubber materials cannot withstand these high temperatures and therefore cannot meet the requirements. Our silicone gaskets, sealing strips, and various rubber seals are made of premium silicone rubber, offering excellent heat and fire resistance. They maintain stable elasticity and excellent sealing performance even at high temperatures, without softening, melting, hardening, cracking, or developing odors. This is why they are widely used in ovens, heating appliances, industrial high-temperature equipment, and other heat-generating devices to solve sealing problems in high-temperature operating environments.

High-temperature silicone rubber gaskets made of ordinary silicone can withstand continuous temperatures up to 230°C, maintaining flexibility and sealing even after prolonged exposure to high temperatures. If you require higher temperature resistance, insulation, or fire resistance, we can use special grades of silicone rubber to manufacture your products, capable of withstanding continuous temperatures up to 300°C. Silicone rubber is also available in specifications that meet FDA and medical industry standards. It can be made of 100% food-grade safe silicone rubber, which does not release harmful substances when heated. It is widely used in air fryers, steamers, sterilizers, microwave ovens, food baking equipment, medical high-temperature sterilization equipment, etc., ensuring long-term reliable and safe operation.
