Product Description
Precipitated silica, also known as hydrated silica or white carbon black, is an important inorganic chemical product. Its main component is silicon dioxide (SiO2), often containing a certain amount of bound water, which can be expressed as SiO2·nHO. It appears as a white amorphous powder, being non-toxic, odorless, insoluble in water and most organic solvents.

Application
Precipitated silica serves as an outstanding filler for paper manufacturing. By filling in the voids among paper fibers, it effectively enhances the opacity, whiteness, and smoothness of paper. Moreover, it bolsters the strength of paper, reducing the likelihood of damage during the processes of printing and writing. Precipitated silica finds widespread use in the production of both cultural paper, like that for books and magazines, and packaging paper, such as the kind used for cartons and boxes.
Fumed silica acts as a powerful reinforcing agent and can significantly improve the physical and mechanical properties of rubber. When it comes into contact with the rubber's molecular chains, it generates physical or chemical cross - linking points. These cross - linking points effectively enhance the rubber's tensile strength, tear resistance, and abrasion resistance. In tire manufacturing, adding fumed silica to rubber leads to tires with better puncture - proof and anti - wear properties. As a result, the tires' service life is extended, and the safety level is increased.
When fumed silica is incorporated into plastics, it has the ability to enhance the strength, hardness, and toughness of these materials. Take, for instance, engineering plastics like polyamide (PA) and polycarbonate (PC). Once fumed silica is added to them, the tensile strength and flexural modulus of the plastics experience a remarkable boost. This improvement allows the plastics to endure much greater external forces, remaining free from deformation or damage even under significant stress.
