It is silicone. Silica gel is a highly active adsorption material, an amorphous material, and its chemical molecular formula is mSiO2·nH2O. It is insoluble in water and any solvent, non-toxic, tasteless, chemically stable, and does not react with any substances except strong alkali and hydrofluoric acid.
Various types of silica gel have 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 are difficult to replace with other similar materials: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc.

Silicone products can be divided into:
1. Molded silicone products
Molded silicone products according to different molding processes It is usually formed by placing solid silicone raw materials with a vulcanizing agent in a high-temperature mold and then applying pressure through a vulcanization machine to solidify the high-temperature sulfur. The hardness of molded silicone is usually between 30°C and 70°C. The raw materials are combined with the color paste to adjust the color according to the Pantone color card number. The shape of the mold determines the shape of the molded silicone products. Molded silicone products are the most widely used in the silicone industry.
2. Extruded silicone products
Extruded silicone products are usually formed by extruding silicone through an extrusion machine. Generally, the shape of extruded silicone is long, and tubular shapes can be optional. Cutting, but the shape of extruded silicone has limitations, and it is widely used in medical devices and food machinery.
