Performance of Colloidal Silica


Colloidal Silica products are basic structural units ofColloidal Silica  chain consisting of the side chain of Colloidal Silica atoms through a variety of organic groups with other connected. Therefore, the structure of silicone products contain both "organic groups", but also contain "inorganic structure", this particular set of composition and molecular structure of organic matter it's features and functionality in an inorganic. Compared with other polymer materials, silicone products, silicone
The most outstanding performance are: 1. Temperature characteristics of silicone products based on silicon - oxygen (Si-O) bond as the main chain structure, C-C bond energy of 82.6 kcal / mole, Si-O bond in silicone for 121 kcal / mole, so the  Colloidal Silicaproducts high thermal stability, high temperature (or radiation) molecular bond is not broken, do not break down. Silicone not only temperature, but also low temperature, in a wide temperature range. Both physical and mechanical properties or chemical properties, with the temperature changes are small. 2. Weathering products of Colloidal Silica main chain-Si-O-, unparalleled key exists, it can not easily be decomposed by UV light and ozone.Colloidal Silica  polymer material better than other thermal stability and resistance to radiation and weathering capabilities. Silicone in the life of the natural environment of up to several decades.
