The temperature resistance of ordinary silica gel is generally in the range of -40℃~160℃. Such ordinary silica gel is generally used as silica gel accessories and silica gel gifts. The ambient temperature usually used is normal temperature, so it does not need high temperature resistance properties.

But such as silicone bakeware, silicone kitchenware often want to use the silica gel products under the environment of high temperature needs to be made of food grade silica gel, because the food grade silica gel in the scope of heat-resistant and 40 ℃ ~ 250 ℃, the general baking and cooking also can't reach 240 ℃, so made of food grade silicone baking tools and silicone kitchen utensils are very safe.

Special high temperature resistant silica gel can reach 350 degrees. High temperature resistant silica gel with phenyl silicone rubber, gas phase silica black as the main raw materials, supplemented by high temperature resistant additives refined, so that the product high temperature resistance to 300-350℃, without two curing, high tear strength, good resilience, not easy to yellowing, feel good;

In ozone, radiation environment is not easy to be oxidized, degradation, good chemical stability; With excellent hate water, moisture-proof, seismic and physiological inertia. High temperature resistant silica gel products use: the product can be molded, extrusion, used for manufacturing chuck, electronic device tray, miscellaneous parts, pipe, oven sealing strip, high temperature resistant protective cover and other high temperature resistant silica gel products.

Advantages of high temperature resistant silica gel:

1. High and low temperature impact resistance

2. Quick vulcanization

3. Very low smell, vulcanization, release harmless to human body

4. Bond to various substrates without using primers

5. Excellent heat resistance, ozone resistance and chemical resistance

6. Excellent electrical insulation performance
