Silica gel can be classified according to various characteristics:

1.According to different composition, it can be divided into: one-component and two-component silica gel.
2.According to the vulcanization temperature, it can be divided into: high temperature vulcanization and room temperature vulcanization silica gel.
3.According to the form of the product, it can be divided into liquid and solid silica gel.
4.According to the vulcanization reaction, it can be divided into: condensation reaction type, platinum addition reaction type and peroxide curing type.
5.According to the main chain structure, it can be divided into: pure silica gel and modified silica gel.
6.According to product characteristics, it can be divided into: high and low temperature resistant type, anti-static type, oil and solvent resistant type, conductive type, foamed sponge type, high-strength tear-resistant type, flame-retardant type, low compression deformation type, etc.
