As a high molecular polyorganosiloxane, silica gel can obtain special functions by adding other groups. For example, after improvement, the low temperature resistance can reach -70 °C, the high temperature resistance can reach 350 °C, and it also has radiation resistance, compression deformation resistance, resistance to Static electricity, oil and solvent resistance, tear resistance and other functions can also meet the environmental protection requirements of non-toxic and tasteless. Many people know about silica gel, but they don't know about silica gel. The following explains the functions of silica gel raw materials:

1. Silicone has high and low temperature resistance. Silica gel has obvious high temperature resistance ability. The silicon atom is mainly connected to the methyl group, the molecule is in a helical structure, and the bond angle and bond length are relatively large. This unique molecular structure makes it have high thermal stability. Generally, silica gel can have a service life of 20 years under the condition of 120 ° C, and our specially formulated silica gel can withstand higher temperatures.

2. Silicone has chemical resistance. Silica gel can quickly restore its own function after oily substances or polar solvents volatilize, and can avoid softening and swelling, so it has excellent chemical resistance and little volume change.

3. Silica gel has low surface activity and physiological inertness. As a semi-inorganic polymer material, silica gel is an inactive compound. Through our special modification, it can achieve the functions of fire retardant, flame retardant and anti-aging. Combined with factory vulcanization, it can achieve green environmental protection, non-toxic and tasteless, and it is basically harmful to the environment and human body. harmless. Because of the flexibility of the molecular chain of silica gel, it also has excellent lubricating and anti-sticking, hydrophobic defoaming and other excellent characteristics.

4. Silicone is resistant to compression deformation. Regardless of the harsh environment of high temperature or low temperature, silicone has excellent anti-compression deformation function, can maintain a good stable state, and can also prepare products with higher requirements according to customer requirements, such as used in sealing rubber rings and the like The product.
