600‑mesh Calcium Carbonate Powder is an important filler for WPC door extrusion, widely used in building‑material industry. It features low impurity content and uniform particle‑size distribution. When added into WPC‑PVC formula, it effectively reduces production cost and improves rigidity, hardness and dimensional stability of profiles.

For WPC door production, it has good compatibility with PVC resin powder, stabilizers, processing aids, lubricants and other additives. Proper filling optimizes processing performance and reduces shrinkage & deformation of finished products. Sealed moisture‑proof storage is required to prevent bad influence on extrusion.
