Silica is a synthetic product and is a hydrated silica. White carbon black is similar in appearance and function to carbon black. Therefore it is called white carbon black. It is a white loose powder, light in weight, large in specific area, and has large adsorption capacity and dispersing capacity.

The price difference of white carbon black in the market can reach ten times, because the production process and quality of the products are different. Generally speaking, it is divided into fumed silica and precipitated silica. Fumed silica is mostly imported and the price is high. Most of the domestic is precipitated white carbon black. The domestic production process of precipitated silica is also divided into two types, standard method and special method. The price of silica produced by special methods is often twice that of standard methods.

Different pesticide formulations have different requirements, and everyone needs to choose products with high cost performance. The functions in pesticide formulations due to limited levels can be summarized as follows:

In solid pesticide solid preparations, such as WP WDG as a carrier, can improve wetting, suspension and storage stability.
