Shanghai food-grade silicone O-ring manufacturer direct

Silica gel (Silica gel; Silica) Alias: Silicone rubber is a highly active adsorption material is amorphous material, its chemical formula is mSiO2 · nH2O. Insoluble in water and any solvent, non-toxic, odorless, chemically stable, it does not react with any substance except alkali, hydrofluoric acid. Various types of silicone because different manufacturing methods form different pore structure. Chemical composition and physical structure of silica gel, determines that it has many other features of similar materials difficult to replace obtained: adsorption properties, thermal stability, chemical stability, high mechanical strength. Silica according to the size of the aperture is divided into: large pore silica gel, rough hole silica gel, B type silica gel, pore silica gel.
