Advantages and characteristics of silica

Transparent solid colloidal nanoparticles (particle size less than 100nm) are non-toxic and have a huge specific surface area. Gas phase white carbon black is entirely made of nano silica, with a purity of up to 99% and a particle size of 10-20nm. However, the preparation process is complex and expensive; Precipitation method silica can be further divided into traditional precipitation method silica and special precipitation method silica. Precipitated silica is mainly used as a reinforcing agent for natural rubber and synthetic rubber, as well as a friction agent for toothpaste. Vapor phase silica is mainly used as reinforcing agent, coating and unsaturated resin thickener of silicone rubber, and ultra-fine silica gel and aerogel are mainly used as coating matting agent, thickener, plastic film opening agent, etc


White carbon black, as an environmentally friendly and high-performance additive, is mainly used in rubber products (including high-temperature vulcanized silicone rubber), textiles, papermaking, pesticides, and food additives.


Rubber products

White carbon black is used in colored rubber products to replace carbon black for reinforcement, meeting the needs of white or semi transparent products. Silica also has super adhesion, tear resistance, heat resistance and aging resistance, so it can also replace part of carbon black in black rubber products to obtain high-quality rubber products, such as off-road tires, engineering tires, radial tires, etc.


Daily chemical products

Transparent colored and opaque toothpastes with white carbon black as filler and abradant have good flexibility, dispersibility, smoothness, softness, good abrasiveness, and do not abrade the toothpaste tube; It can maintain the stability of medicinal toothpaste. Especially with fluoride, it has good compatibility and can avoid the disadvantage of insoluble salts produced by calcium salts as abrasives.

Cementitious agent

Used in adhesives made of natural rubber or synthetic rubber, it provides thixotropy and reinforcement, while also improving adhesion due to its extensibility, making it high-quality and cost-effective.


Paper filler
Using white carbon black as a paper filler can improve the ink penetration resistance and mechanical strength of the paper, increase whiteness, and reduce unit weight. It can effectively achieve paper lightweight, reduce production costs, and improve paper performance.
