Audited Supplier | Light calcium carbonate is a micron-scale precipitated calcium carbonate, which is a white odorless powder or slurry prepared by carbonation precipitation reaction, dehydration, drying and crushing. Its outstanding features are high whiteness, high purity and good dispersion. "Warner" brand light calcium carbonate has a high retention rate in paper filling or coating, which can effectively improve the brightness, whiteness, strength and bulk of paper products. It is widely used in coatings, plastics and rubber products, filling and replacing higher-priced resins and titanium dioxide, which can reduce the economic cost of product processing, and can give products with ideal thickening, anti-settling, impact resistance, bending modulus, Dimensional stability and product appearance. |

| The product is made of high-quality calcium carbonate raw material, and adopts advanced production technology, which is finely activated and coated on the surface. The product has the characteristics of good fluidity, good dispersion, and strong fusion with the matrix resin. Mainly used in plastics, rubber, ink, building materials and other industries. |
| Light calcium carbonate is used as a filler in rubber, which can serve |
| 1 Increase the volume |
| 2. Reduce costs, |
| 3. Improve processing performance and vulcanization performance; |
| In plastic: |
| 1 can improve the dimensional stability, hardness and rigidity of plastic products, |
| 2 Improve the processing performance of plastics and the heat resistance and astigmatism of its products, such as PVC cable materials, ABS polyurethane, polystyrene polyester, polyamide, polyethylene, polypropylene, |
| 3 can greatly increase the filler material and improve the processing performance of the article, |
| 4 Improve product quality and reduce production costs; |
| As a filler in the ink, it plays a skeleton role, so it is called "body pigment"; |
| In oil-based paints, the filling amount can reach 10-50%. |
| Packing: | 50KGs Iron Drum or 1000KGs Jumb Bag or packing as per request. |
| Storare: | Storing in sealed, dry and cool condition, not exposing to air for long time, avoiding moisture. |
| Characteristics: | Pink powder, slightly soluble in inorganic acid, insoluble in water. |
