The temperature resistance range of ordinary silicone is generally between -40 ℃ and 160 ℃. Such ordinary silicone is commonly used as silicone accessories and gifts, and the ambient temperature is usually room temperature, so it does not require high temperature resistance properties.
However, silicone products such as silicone baking utensils and silicone kitchenware, which are often used in high-temperature environments, need to be made of food grade silicone because the temperature resistance range of food grade silicone is around -40 ℃ to 250 ℃, and general baking and cooking will not reach 240 ℃. Therefore, baking tools and silicone kitchenware made of food grade silicone are very safe.
Special high-temperature resistant silicone can reach 350 degrees.
High temperature resistant silicone is mainly made of phenyl silicone rubber and gas-phase white carbon black as the main raw materials, supplemented by high temperature resistant additives to refine the product. The product can withstand high temperatures up to 300-350 ℃ without the need for secondary vulcanization, with high tear resistance, good resilience, and is not prone to yellowing and good texture; Not easily oxidized or degraded in ozone and radiation environments, with good chemical stability; Has excellent hydrophobicity, moisture resistance, shock resistance, and physiological inertness. Application of high-temperature resistant silicone products: This product can be molded and extruded, used for manufacturing high-temperature resistant silicone products such as suction cups, electronic device trays, miscellaneous parts, pipes, oven sealing strips, and high-temperature protective sleeves.
Advantages of high-temperature resistant silicone:
1. Resistance to high and low temperature impacts
2. Rapid vulcanization
3. Extremely low odor, released harmless to the human body during vulcanization
4. Bond with various substrates without using primer
5. Excellent heat resistance, ozone resistance, and chemical erosion resistance
6. Excellent electrical insulation performance
