Silicone gel (Silica gel; Silica) alias: Silicone rubber is a highly reactive adsorbent material, is an amorphous material, its chemical molecular formula is mSiO2-nH2O. insoluble in water and any solvent, non-toxic, tasteless, chemically stable, in addition to the strong alkali, hydrofluoric acid, does not react with any substance.
Various models of silica gel have different microporous structures due to their different manufacturing methods.
Silica gel's chemical composition and physical structure, it has many other similar materials difficult to replace the characteristics: high adsorption performance, good thermal stability, chemical stability, high mechanical strength. Silicone according to the size of its pore size is divided into: large pore silica gel, coarse pore silica gel, B-type silica gel, fine pore silica gel.
Rubber is, extract the latex of rubber trees, rubber grass and other plants, processed and made of elastic, insulating, impermeable to water and air. Highly elastic polymer compounds. Divided into natural rubber and synthetic rubber two kinds.
Natural rubber is extracted from rubber trees, rubber grass and other plants made of gum after processing; synthetic rubber by a variety of monomers by polymerization reaction. Rubber products are widely used in all aspects of industry or life.
