400 Mesh Dolomite Powder

Product Performance & Advantages
400 mesh dolomite powder is finely ground and multi-layer precisely screened, with pass rate stably reaching 92%-99.993% and no coarse particles. Compared with 200 mesh coarse powder, it has finer texture, better product surface flatness and higher modification accuracy; compared with fine mesh powder, it has larger filling capacity and lower production cost. With fixed standard calcium oxide content, it has stable acid and alkali resistance and weather resistance. It can effectively improve product rigidity, dimensional stability and wear resistance, optimizing production formula and reducing comprehensive costs.

Application Scope
Widely used in general modified plastics, PVC/PP/PE products, rubber filling and reinforcement, EVA foaming materials. In chemical industry, it serves as core filler for industrial coatings, architectural water-based paints, adhesives and sealants. It is also applicable for papermaking filling, daily chemical auxiliaries, building materials and ceramic raw material processing, covering most conventional industrial filling scenarios.
