Uncoated Calcium Carbonate Precipitated Light (PCC), Calcium Carbonate, is a high-purity white fine powder used as a cost-effective filler. It improves brightness, smoothness, and strength in plastics, paints, rubber, paper, and PVC industries, offering excellent dispersion and consistent performance in various industrial applications.
Chemical Formula: CaCO₃
Appearance: Ultra-fine white powder
Uncoated Calcium Carbonate (Precipitated Light) is a high-purity, finely processed mineral widely used as a functional filler in plastics, paints, rubber, paper, pharmaceuticals, and various industrial applications. It is produced through a controlled chemical precipitation process, resulting in extremely fine particle size, high brightness, and excellent uniformity.
Unlike coated grades, this product is uncoated PCC (Precipitated Calcium Carbonate), making it highly compatible with water-based systems and ideal for applications where surface treatment is not required. Its superior whiteness, controlled particle size, and consistent quality make it a preferred choice in modern manufacturing industries.
Precipitated Calcium Carbonate is composed of calcium, carbon, and oxygen in a stable crystalline form.
CaCO₃
It is chemically stable, non-toxic, and insoluble in water. The controlled precipitation process allows precise control over particle size and morphology, resulting in improved performance in industrial applications.
Uncoated PCC offers several important industrial properties:
These properties make it suitable for a wide range of industries requiring high-quality filler performance.
Precipitated Calcium Carbonate is produced through a chemical process involving limestone:
This controlled process ensures uniform particle size, high purity, and excellent brightness.
Used as a filler in PVC, polyethylene, and polypropylene products to improve stiffness, reduce cost, and enhance processing efficiency.
Acts as an extender pigment to improve opacity, whiteness, and surface smoothness in water-based and solvent-based paints.
Improves brightness, printability, and surface quality in paper production.
Enhances mechanical strength, wear resistance, and processing performance.
Improves viscosity control and filler performance.
Used as a calcium supplement and excipient in controlled formulations.
Uncoated PCC works primarily as a functional filler and extender. Its ultra-fine particles fill gaps within polymer, paint, or paper matrices, improving density, opacity, and surface finish. Because it is uncoated, it disperses easily in water-based systems, making it highly suitable for emulsions and aqueous formulations.
Uncoated calcium carbonate is non-toxic and safe to handle under normal industrial conditions.
Uncoated Calcium Carbonate (Precipitated Light) is a high-quality, ultra-fine mineral widely used as a versatile filler in plastics, paints, paper, rubber, and chemical industries. Its excellent brightness, fine particle size, and superior dispersion properties make it an essential raw material in modern manufacturing. With consistent quality, cost efficiency, and broad industrial compatibility, it remains one of the most important functional fillers in global industrial applications.
