Generally, the temperature of ordinary silica gel is in the range of -40 ° C ~160 ° C, such ordinary silica gel is generally used as silicone accessories, silicone gifts are more, and the ambient temperature is usually used at room temperature, so it does not need high temperature resistance properties.
However, such as silicone baking utensils, silicone kitchenware, which are often used in high temperature environments, silicone products need to be made of food-grade silicone, because the temperature range of food-grade silicone is about -40 ° C ~250 ° C, and general baking and cooking will not reach 240 ° C, so 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 silica gel with phenyl silicone rubber, vapor phase carbon black as the main raw materials, supplemented by high temperature additives refined, so that the product high temperature resistance to 300-350℃, no need for secondary vulcanization, high tear strength, good resilience, not easy to yellow, feel good;
It is not easy to be oxidized and degraded in ozone and radiation environment, and has good chemical stability. It has excellent hydrophobic, moisture-proof, anti-seismic and physiological inertia. High-temperature silicone product use: The product can be molded and extruded for the manufacture of suction cups, electronic device trays, miscellaneous parts, pipes, oven seals, high-temperature protective sleeves and other high-temperature silicone products.
High temperature silicone advantages:
1. High and low temperature impact resistance
2. Fast vulcanization
3. Very low odor, vulcanization, release harmless to the human body
4. Bond with various substrates without the use of primer
5. Excellent heat resistance, ozone resistance and chemical erosion resistance
6. Excellent electrical insulation performance
