1. Heat resistance: Silica gel is much better than ordinary rubber in heat resistance, it can be used almost forever at 150, with no performance change, it can be used continuously for 10,000 hours at 200, and it can be used for a period of time at 350°.

2. It is widely used in heat resistant situations, such as thermostable handle of thermostable sealing ring of thermostable bottle ring and pressure cooker ring.Cold resistance: normal rubber is -20° to -30°, that is, silica gel has good elasticity when -60° to -70°. Some special formulations of silicone rubber can also withstand extremely low temperature, such as: low temperature sealing ring.Sealing: it has good sealing performance.

3. Aging resistance: no yellowing or fading after long-term use.

4. Safety: The raw materials are made of food-grade silica gel. The products are tasteless and do not deform and produce harmful substances at high temperature.
