The Function of rtv-2 silicone rubber

Why silica in this family seems to be everywhere in it? Then it opened its manual:

　　A heat-resistant cold: silicon products based on silicon - oxygen (Si-O) bond structure of the main chain, C-C bond energy of 82.6 kcal / mol, Si-O bond energy in organic silicon 121 kcal / mole, so the high thermal stability of silicone products, high temperature (or radiation) molecular bond is not broken, do not break down. Silicone not only temperature, but also resistant, silicon is silicon - oxygen (Si-O) bond as the main chain structure, C-C bond energy of 82.6 kcal / mol, Si-O bond The bond energy of organic silicon in the 121 kcal / mol, so the high thermal stability of silicone products, high temperature (or radiation) molecular bond is not broken, do not break down. Silicone is not only to high temperature, low temperature resistance, but also can be used in a very wide temperature range. Therefore, the production of insulating pad is the truth.

　　2 durability and good operating performance: silica gel mobility fit, moderate viscosity easy to brush the mold. Small shrinkage of the silicone rubber. Good tensile silicone rubber. Made out of silicone mold deformation. Product quality feel and excellent ductility material, such as silicone coasters and table mats, which play a strong friction to prevent the glass, porcelain slip. Also a role in protecting the desktop in order to avoid scratches, burns.

　　3 weathering characteristics: the product of the main chain-Si-O-, unparalleled key exists, it is not easy to be decomposed by ultraviolet light and ozone. Better than other silicone polymer material thermal stability and resistance to radiation and weathering capabilities. Silicone natural environment relatively long life in general.

　　4 high adsorption capacity: silicone with an open porous structure, strong adsorption, can absorb a variety of substances. As absorb moisture, moisture is about 40%. With silanol groups on the silica surface, the adsorption performance and the performance by the formation of hydrogen bonds with the polar-OH group of the compound or a silicon atom on the unsaturated compound. Can absorb water to form hydrated silica silanol. When the saturated water absorption, and the change in surface morphology does not occur. So it can be used to produce some of the desiccant.

　　5 excellent insulating properties: silicone products have good electrical insulation properties, dielectric loss, resistance, voltage, resistance, arc resistance, corona resistance, volume resistivity and surface resistivity of the top in the insulating material etc., but also has excellent water repellency, which is an electrical device used in wet conditions with a guarantee of high reliability.
