Silicone (silica gel),aliased as silicone rubber,is a highly active adsorbent material, which is an amorphous material whose chemical molecular formula is mSiO2· nH2O.
Silicone is insoluble in water and any solvent, non-toxic and tasteless, chemical properties stable, except strong alkali, hydrofluoric acid not react with any material.
According to its aperture,silicone can be divided into following types:macroporous silicone, coarse porous silicone, type B silicone, fine porous silicone.Different types of silicone have different microporous structures due to different manufacturing methods.
Chemical components and physical structure of the silicone, determines it has many other features of similar materials difficult to replace, high adsorption properties, thermal stability, chemical stability, has high mechanical strength, etc.
