In general, the silicone can be classified according to the nature and composition of organic silica and inorganic silicone two categories. Shape into its composition silicone extrusion and molding silicone .

Inorganic silica is a highly active adsorption material , usually with sodium silicate and sulfuric acid , and after a series of aging process , acid bulbs and prepared. An amorphous silica material , its chemical formula is mSiO2. nH2O. Insoluble in water and any solvent , non-toxic , odorless , chemically stable , does not react with any substance except alkali, hydrofluoric acid . Various types of silica because of the way they are formed of different porous structures . Chemical composition and physical structure of the silica gel , determines that it has many other similar materials difficult to replace characteristics: high adsorption properties, good thermal stability , chemical stability , high mechanical strength.

Silicone is an organic silicon compound , are those containing Si-C bond , and at least one organic group is a compound directly bonded to silicon atoms , it is customary to those often via an oxygen , sulfur , nitrogen and other organic radicals to silicon compound atom also connected as an organic silicon compound . Among them, the silicon- oxygen bond (-Si-O-Si-) for the skeleton composed of polysiloxane is the largest number of organic silicon compounds , study the deepest , the most widely used class of more than 90% of the total amount .
Silicone Extrusion more common , such as household electric cooker seals , called silicone ring cooker .
Molded silicone bit more complicated , irregular shape, including silicone bowls, silicone ice lattice, silicone bakeware and more.
