Silicone is a highly active adsorption material, belonging to the amorphous state. It contains polysiloxane, silicone oil, silica, coupling agent and filler, etc. The main component is silica. Insoluble in water and any solvent, non-toxic and odorless, chemically stable, and does not react with any substance except strong bases and hydrofluoric acid. Various types of silica gel form different microporous structures due to their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics that other similar materials cannot replace: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc.

Silicone can be classified according to various characteristics:

It can be divided into single component and dual component silicone according to its composition.
According to the vulcanization temperature, it can be divided into high-temperature vulcanization and room temperature vulcanization of silicone.
According to the form of the product, it can be divided into liquid and solid silicone.
According to the vulcanization reaction, it can be divided into condensation reaction type, platinum addition reaction type, and peroxide curing type.
According to the main chain structure, it can be divided into pure silicone and modified silicone.
According to product characteristics, it can be divided into: high and low temperature resistance type, anti-static type, oil and solvent resistance type, conductive type, foam sponge type, high-strength tear resistance type, flame retardant and fireproof type, low compression deformation type, etc.
