Organic silica gel is an organosilicone compound, which refers to a compound containing Si-C bond, and at least one organic group is directly connected with silicon atoms, and it is customary to often use those compounds that connect organic groups with silicon atoms through oxygen, sulfur, nitrogen, etc., as organosilicon compounds. Among them, polysiloxane composed of silico-oxygen bond (-Si-o-Si -) as the skeleton is the most numerous, the most deeply studied and the most widely used class of silicone compounds, accounting for more than 90% of the total dosage. Raw materials are mainly divided into silicone rubber, silicone resin, silicone oil, silane.

The raw rubber of silica gel before vulcanization has a linear molecular structure, and the cooked rubber after vulcanization is a three-dimensional elastomer with a network. Silica gel is precisely because of its special molecular structure, so that it has better antioxidant capacity and higher stability

Silicone can be classified according to various characteristics:
1, according to the composition can be divided into: single component and two-component silicone.

2, according to the vulcanization temperature can be divided into: high temperature vulcanization and room temperature vulcanization silicone.

3, according to the shape of the product can be divided into: liquid and solid silica gel.

4, according to the vulcanization reaction can be divided into: condensation reaction type, platinum addition reaction type and peroxide consolidation type.

5, according to the main chain structure can be divided into: pure silica gel and modified silica gel.

6, according to product characteristics can be divided into: high and low temperature resistance type, anti-static type, oil and solvent resistance, conductive type, foam sponge type, high strength tear resistance type, flame retardant fire protection type, low compression deformation type.
