The advantages of silicone rubber are heat resistance, Du cold resistance, dielectric property, ozone resistance and atmospheric aging resistance. The outstanding performance of silicone rubber is that it can be used for a long time from – 60 ℃ (or lower temperature) to + 250 ℃ (or higher temperature). The disadvantages of silicone rubber are: the mechanical properties such as tensile strength and tear strength are poor, its physical and mechanical properties are inferior to most synthetic rubber at room temperature, and the general silicone rubber has poor oil and solvent resistance except nitrile silicone and fluorosilicone rubber.

1, silica gel Name: silica gel, is a highly active adsorption material, is an amorphous material. The main component of silica gel is silica, which has stable chemical properties and does not burn.

2. The main component of silica gel is silica, which has stable chemical properties and does not burn. Silica gel is a kind of amorphous silicon dioxide, the dust content of workshop should be controlled not more than 10 mg / m3, ventilation should be strengthened, and masks should be worn during operation.

3. Silica gel has a strong adsorption capacity and can produce drying effect on human skin. Therefore, work clothes should be worn during operation. If silica gel gets into the eyes, rinse with plenty of water and see a doctor as soon as possible.

4. Blue silica gel contains a small amount of cobalt chloride, which has potential toxicity. It should be avoided to contact with food and inhaled. In case of poisoning, seek medical treatment immediately. Silica gel can be reused after regeneration due to its adsorption of water vapor or other organic substances in the medium.

5. Generally speaking, silica gel can be divided into organic silica gel and inorganic silica gel according to their properties and components.
