The excellent performance of organic silica gel is?

The basic structural unit of organic silicon products is composed of silicon and oxygen chain structure, while the side chain is connected with other organic groups through silicon atom. Therefore, in the structure of silicone products contains both organic groups, but also contains the "inorganic structure", the special composition and molecular structure makes it organic matter characteristics and inorganic feature set in a body. Compared with polymer materials, the most outstanding performance of silicone products is:
A. electrical insulation performance
Silicone products have good electrical insulation properties, the dielectric loss, resistant to voltage, arc resistance, corona resistance, volume resistivity and surface resistivity etc. were in insulating materials is one of the top and their electrical properties by the influence of temperature and frequency is very small. As a result, they are a stable electrical insulation material, which is widely used in electronic and electrical industry. In addition to having excellent heat resistance, organic silicon has excellent water repellent property, which is the guarantee for the use of electrical equipment with high reliability under wet condition.
B. heat resistance
Organic silicon product is silicon - oxygen (SiO) key backbone structure, C-C bond bond to 82.6 thousand cards / mole, SiO bond bond to 121 thousand card in the silicone / mole, so the high thermal stability of silicone products, high temperature (or radiation) molecular chemical bond not broken, do not break down. Silicone is not only resistant to high temperature, and low temperature resistance, can be used in a wide temperature range. Whether chemical or physical mechanical properties, with the change of temperature are very small.
C. low surface tension and low surface energy
Organic silicon main chain is very soft, the intermolecular force than hydrocarbons to much weaker. Therefore, the ratio of the viscosity of the hydrocarbons with molecular weight low, weak surface tension, the surface can be small, film forming ability. This low surface tension and low surface energy is the main reason for its application in many aspects: hydrophobic, foam, foam stability, anti stick, lubrication, polishing, etc..
D. climate resistance
Silicone products main chain Si O, no double bond exists, it is not easy to be decomposed by ultraviolet and ozone. Silicone has better thermal stability and resistance to irradiation and weathering than other polymer materials. The service life of the natural environment in organic silicon can reach several tens years.
E. physiological inertia
The polysiloxane compound is a compound known to most inactive in. They are very resistant to aging, and have no rejection reaction with animals, and have good anti coagulation performance.
