CaCO3 CAS 471-34-1 Powder Industry Grade for Rubber Chemical Auxiliary Agent Non Black Filler Calcium Carbonate Update 10.28
Product Description
Physical Properties
Appearance: Pure products are white, odorless powders or crystals, non-toxic, and friendly to humans and the environment.
Solubility: Almost insoluble in water, easily soluble in strong acids, and produces carbon dioxide gas when in contact with acids (this is a typical characteristic that distinguishes it from other calcium salts).
Stability: Stable under normal temperature and pressure; decomposes into calcium oxide (quicklime) and carbon dioxide at high temperatures (above approximately 825°C), and can be used as a raw material for industrial alkali production or calcium supplements.

Application
Calcium Carbonate Application:
1. Industry and Manufacturing
Plastic/Rubber Filler: Used as a low-cost filler in plastics (e.g., PVC pipes) and rubber products. It enhances product hardness and wear resistance while reducing raw material costs.
Coating/Ink Additive: Serves as an extender pigment in latex paints and industrial coatings. It improves the hiding power and leveling property of coatings, and also enhances the weather resistance (UV resistance, anti-aging) of the coating film.
Paper Industry: Applied in paper sizing and filling processes. It increases paper whiteness and smoothness, reduces pulp consumption, and is a key raw material for the production of cultural paper and packaging paper.
2. Construction and Building Materials Sector
Cement/Concrete Raw Material: Natural limestone is a core component for cement production. It is calcined with clay and other materials to form cement clinker. It can also be directly ground into fine powder and mixed into concrete to improve concrete strength and impermeability.
Wall Materials: Used in the production of lightweight partition boards, aerated bricks, etc. By utilizing its heat resistance and sound insulation properties, it reduces the weight of walls while achieving environmental protection and energy conservation.
Packaging & Shipping
Calcium Carbonate Packaging and Shipping:
Storage Requirements
1. Must be stored in a cool and dry warehouse. Avoid open-air stacking or proximity to water sources (though it is not easy to absorb moisture, long-term humidity may cause caking);
2. It is strictly prohibited to store together with strong acids to prevent reactions that cause product deterioration;
3. The shelf life of unopened products is usually 2 years. After opening, they should be used as soon as possible and the bag mouth should be sealed
