What is carbon black?

White carbon black, in foreign countries commonly known fumed silica, precipitated silica, it is a general term for amorphous silica and silicates, in our country commonly called fumed silica, precipitated silica.
White carbon black is white powder granular, non-toxic, tasteless, with good physiological inert, insoluble in water, solvent and acid, but soluble in hydrofluoric acid and alkali. White carbon black of the structure and the application performance and carbon black are similar, the appearance of carbon black is black, and the appearance of white carbon black is white, it is called white carbon black.

Silica is an important chemical product in recent years, the state vigorously support in terms of policy. The "Eleventh Five Year" chemical industrial technology development program "will be included in the priority development areas, the China rubber industry" Eleventh Five Year "scientific development planning advice" clearly put forward to actively support the radial tire specific silica production, to have conducive to safety, energy saving and low rolling resistance. The national industrial policy support, provides a broad space for the development of carbon black industry.
White carbon black is very versatile, as reinforcing agent in the rubber and tire, as a dispersing agent and carrier is widely used in medicine, pesticide, solid pure fire wood, paint and ink, can also be used in pesticides, feed as carrier or as a flow aid, in toothpaste used as friction agent and a thickening agent, in the paint for the settlement agent and matting agent, in the paper as filler.
Gas phase white carbon black can also be used as a multifunctional additive, widely used in cable material, adhesive, coating, printing ink, food and cosmetics, to reinforcing, thickening, anti caking, control the rheological and thixotropic etc..
The variety of silica in China is still in the universal product, mostly belong to the middle and low product application basically stay in common use, applicable to green tire with the high dispersion varieties, silicone rubber with high transparent products, high-grade flatting agent special varieties still need to import, these high added value products on behalf of the silica development important direction. In the adhesives and sealants, white carbon black mainly as reinforcing agent and mobile agent, to control flow, to prevent the settlement, to prevent sagging and reinforcing effect.
In addition, the application of silica in inks and coatings widely, mainly as rheological agent, anti settling agent, dispersant. (source: Global silicone mesh)
