Silica can be used as a filling material in plastic production, which can improve the elastic strength and wear resistance of plastics, as well as the thermal stability of hardness. In addition, the use of white carbon black in cables can also improve the electrical insulation of cables, such as the use of gas-phase white carbon black or high-quality precipitated white carbon black for vinyl silicone rubber high-voltage wires. It is often difficult to separate between two layers of plastic film, and it is difficult to open the bag opening when bagging, so white carbon black is a very useful opening agent.


Application:

1. Rubber products: Silica 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.


2. Agricultural chemicals: In agricultural chemicals, such as pesticides and high-efficiency fertilizers, Silica is used as a carrier, diluent, or disintegrating agent. When used as a disintegrating agent in water dispersible granule agent wdg, the suspension rate can be increased, and it is recommended to use a content of about 10%. It can maintain lasting effect because of its super high surface area, high adsorption, easy suspension, good affinity and chemical stability. Even under rain, flushing, and hot conditions, it can remain unchanged for a long time.


3. Daily chemical products: Transparent colored and opaque toothpastes with white carbon black as filler and abradant. This type of toothpaste has good flexibility, dispersibility, smooth and soft paste, good abrasion resistance, and does not abrade the toothpaste tube body; 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.


4. Cementitious agent: It is used in adhesives made of natural rubber or synthetic rubber, providing thixotropy and reinforcement. At the same time, because of its extensibility, it can also improve the adhesion, with high quality and low price.


5. Anticaking agent: white carbon black can be used in some products to improve free flow, such as grass fertilizer, fungicide, grinding wheel abrasive, laundry bleach, phenolic injection molding urotropine, plastic products of phenol and urea, manufacturing rubber sulfur and anti caking mixture.


6. Paper filler: Using white carbon black as 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. In addition, it can also be used in many industries such as fire extinguishing agents, feed, cosmetics, matting agents, pigments, paints, etc.
