Generally, the temperature resistance range of ordinary silicone rubber is -40°C~160°C. Such ordinary silicone rubber is generally used as silicone rubber accessories and silicone rubber gifts. The ambient temperature usually used is normal temperature, so it does not need a high temperature High temperature resistant properties.
However, silicone rubber products such as silicone rubber baking utensils and silicone kitchen utensils, which are often used in high-temperature environments, need to be made of food-grade silicone rubber, because the temperature resistance range of food-grade silicone rubber is around -40°C~250°C. General baking and cooking will not reach 240°C, so baking tools and silicone kitchen utensils made of food-grade silicone are very safe.
Special high temperature resistant silicone rubber can reach 350 degrees. High temperature resistant silicone is made of phenyl silicone rubber and fumed silica as the main raw materials, supplemented by high temperature resistant additives, so that the product can withstand high temperature up to 300-350 ° C, without secondary vulcanization, high tear strength and resilience Good resistance, not easy to yellow, good hand feeling;
It is not easy to be oxidized and degraded in the environment of ozone and radiation, and has good chemical stability; it has excellent hydrophobicity, moisture resistance, shock resistance and physiological inertia. Application of high-temperature-resistant silicone products: This product can be molded and extruded to manufacture high-temperature-resistant silicone products such as suction cups, electronic device trays, miscellaneous parts, pipes, oven sealing strips, and high-temperature resistant protective covers.
Advantages of high temperature resistant silicone:
1. High and low temperature impact resistance
2. Rapid vulcanization
3. Very low odor, when vulcanized, the release is harmless to the human body
4. Adhesive to various substrates without using primer
5. Excellent heat resistance, ozone resistance and chemical corrosion resistance
6. Excellent electrical insulation performance
