Narrow particle size distribution range, reduced water absorption, oil absorption value and good compatibility with resin are conducive to improve the tensile, compressive and wear resistance properties of the products. After mixing, the melting time is shortened, the balance torque is reduced, the dispersion is high, and it is easy to dye, which can increase the surface luster of the products and disperse easily in organic polymers. Other treatment agents can be added according to the needs of users. In the paper industry, it has the requirements of increasing the surface gloss, improving the whiteness and improving the paper surface smoothness.
