White carbon black is a synthetic product and is a hydrated silica. White carbon black is similar to carbon black in appearance and function. It is therefore called white carbon black. For white loose powder, light weight, large specific area, adsorption capacity and dispersion capacity are very large.


The price gap of white carbon black in the market can be up to ten times, because the production process and quality of the product are different. In general, it is divided into vapor phase white carbon black and precipitated white carbon black. Fumed white carbon black is mostly imported and the price is high. Most of the domestic precipitated white carbon black. The production process of precipitated white carbon black in China is also divided into two kinds, which are standard method and special method. The price of white carbon black produced by the special method is often twice that of the standard method.


Different pesticide dosage forms have different requirements, and we need to choose cost-effective products. Due to limited levels, the functions in pesticide preparations are roughly summarized as follows:


In solid pesticide solid preparations, such as WPWDG as a carrier, can improve wettability, suspension and storage stability.


Wettable powder (WP) is a pesticide preparation containing the original agent, carrier and filler, surfactant (wetting agent, dispersant) auxiliary agent and crushed very fine. This preparation, when diluted to a field concentration, forms a stable, spray-ready suspension.
