About silicone gel:   

1. Because of its chemical composition silicone and physical properties of the structure, determines that it has many other features of similar
materials difficult to replace, in the application has the following advantages:
2. Non-toxic, odorless, chemically stable, insoluble in any solvents and solutions, in addition to hydrofluoric acid (HF) and strong base, but does
 not react with any substance.
3. thermal stability, pore type silicone gel can be less than the temperature of 300 °C to use, and other types of silicone gel was able to
500-600 °C long-term use under high temperature conditions.
4. Silicone gel has a rigid frame structure, high mechanical strength, good wear resistance.
5. Silicone non-deliquescent, non-corrosive and non-soluble in water features, even full of water absorption, the look and feel, or dry.
6. Silicone gel with stable quality, and does not use and the external environment changes
