Heat-resistant Silicone Rubber Seal Strips for Oven & Heating Equipment Sealing

Our high-temperature-resistant silicone rubber sealing strips are manufactured using a custom extrusion process and are suitable for sealing applications in various heating and high-temperature equipment. Other rubber compounds and plastic materials rapidly harden, crack, or deform under sustained high temperatures. Silicone possesses many superior properties, one of its key characteristics being its excellent temperature range. It maintains stable elasticity, softness, and excellent sealing performance even under prolonged high-temperature operating conditions. With its outstanding heat, ozone, and aging resistance, it is an ideal sealing solution for high-temperature appliances and industrial equipment.

Standard silicone sealing strips can easily withstand temperatures from -60°C to 200°C. If you require higher heat resistance or fire resistance, we can use special grades of silicone rubber to manufacture your parts. In addition to high-temperature resistance, we also offer FDA-approved silicone materials for food processing applications. Widely used for oven door sealing, disinfection cabinets, steam ovens, air fryers, baking equipment, industrial drying ovens, high-temperature heating cabinets, and other thermal equipment. Perfect for equipment manufacturers who need customized high-temperature silicone strips and silicone gaskets for mass assembly.
