This product is made from fine precipitated Calcium Carbonate. The whiteness can reach 93%. Particle size is fine and average. Having special surface activity, it can be well dispersed in the basic materials. Been widely used in plastic, rubber, and paint industry as filler, it can facilitate the mould release, improve the process ability of products, enhance the surface finish and the flexing resistance, increase the quantity of filler and reduce the production cost.
