ultra fine ground calcium carbonate powder for masterbatch
Ground calcium carbonate also called heavy calcium carbonate.Its chemical formula is CaCO3. Ground calcium carbonate is widely used in engineering plastics, wire and cable, powder coating, oil coating, rolling film, PVC edge banding, corrugated pipe, PVC leather, shoes material, etc.
Ground calcium carbonate features:
For engineering plastics, wire and cable, rolling film, PVC edge banding, corrugated pipe, PVC leather, shoes material: it mainly has the effect of filling, reduce the cost of material, and can improve the hardness and whiteness of materials, improving the function of the mechanical properties, and may improve the bending properties of the material in a certain extent. It recommend to use 2500Mesh or above for the film product with a small thickness to improve the hand feeling of the products.
For powder coating and oily coating: it improve the dry film whiteness, covering and hardness of coating, and reduce the cost of coating. Covering power has improved, but it needs good dispersing equipment or technology.
