High Temperature Resistant Silicone Sheet: Properties and Applications High temperature resistant silicone sheets are versatile industrial materials designed to withstand extreme heat while maintaining flexibility, durability, and electrical insulation properties. These sheets are made from high-quality silicone rubber, which exhibits exceptional thermal stability, chemical resistance, and mechanical performance. Key Properties 1. Thermal Resistance - Silicone sheets can endure continuous exposure to temperatures ranging from -60°C to 250°C (-76°F to 482°F), with some specialized grades resisting even higher short-term peaks (up to 300°C or 572°F). - Unlike organic rubbers, silicone does not harden, melt, or degrade under high heat, making it ideal for demanding environments. 2. Flexibility and Durability - Despite extreme temperatures, silicone sheets retain their elasticity and tensile strength, ensuring long-term performance without cracking or becoming brittle. - They resist compression set, maintaining their shape and sealing properties under prolonged stress. 3. Chemical and Weather Resistance - Silicone is resistant to ozone, UV radiation, moisture, and many chemicals, including acids, alkalis, and solvents. - This makes it suitable for outdoor applications and harsh industrial settings. 4. Electrical Insulation - With excellent dielectric strength, silicone sheets are widely used in electrical and electronic industries to insulate components from heat and electrical currents. 5. Non-Toxic and FDA-Compliant Options - Certain grades meet FDA standards for food contact, making them safe for use in food processing, medical devices, and pharmaceutical applications. Applications - Industrial Gaskets & Seals – Used in engines, boilers, and HVAC systems where high-temperature sealing is required. - Electronics – Protects circuit boards, transformers, and other components from heat and electrical interference. - Automotive & Aerospace – Functions as thermal insulation in engines, exhaust systems, and avionics. - Food & Beverage – Employed in conveyor belts, baking mats, and sealing applications due to non-toxicity. - Medical Equipment – Used in sterilization trays, autoclave gaskets, and other heat-resistant medical devices. Customization Silicone sheets can be fabricated in various thicknesses (0.5mm to 10mm or more), colors, and hardness levels (Shore A 20 to 80). They can also be reinforced with fiberglass or other materials for added strength. Conclusion High temperature resistant silicone sheets are indispensable in industries requiring reliable performance under extreme conditions. Their unique combination of heat resistance, flexibility, and durability ensures efficiency and safety across diverse applications.
