Calcium carbonate (CaCO₃) is one of the most widely used minerals across various industries. Thanks to its high whiteness, purity over 99%, excellent filling properties, and cost-effectiveness, it holds a unique position among industrial raw materials.
Outstanding Whiteness (Whiteness > 95%)
Provides a smooth, glossy, and uniform appearance in paints, resins, compounds, and masterbatches.
High Chemical Purity (>99% CaCO₃)
Extremely low impurities; does not interfere with formulations or chemical reactions.
Excellent Filling Capacity
Significantly reduces the use of expensive raw materials like resins and polymers.
Cost-Effective Alternative to Many Additives
Lowers the final production cost without compromising quality.
Controlled Particle Size Distribution (Mesh 200 to 2500)
Suitable for various production lines – from injection molding to extrusion and surface coating.
Calcium carbonate is one of the most commonly used fillers in the paint and resin industry. With its high whiteness, controlled particle size, low oil absorption, and competitive price, this mineral plays a vital role in improving the final properties of paints.
Benefits:
Enhances paint coverage and opacity
Increases surface brightness and gloss
Reduces consumption of expensive pigments
Stabilizes viscosity
Lowers the overall formulation cost
Using calcium carbonate with the appropriate mesh size—especially in wall paints, industrial coatings, traffic paints, and powder resins—leads to better product quality and lower production costs.
In the polymer and plastic industry, calcium carbonate is widely used as a primary filler in masterbatch, compounds, pipes, sheets, and injection-molded parts. It not only reduces total production costs but also improves mechanical strength, rigidity, and moldability of products.
Benefits:
Reduces base polymer consumption
Improves tensile strength and stiffness
Enhances melt flow and processability
More economical than pure polymers
Choosing the right grade and mesh size of calcium carbonate for each masterbatch or plastic application significantly boosts production efficiency and product quality.
Calcium is essential for bone growth, egg production, and overall physiological performance in livestock and poultry. Calcium carbonate is one of the most cost-effective and bioavailable calcium sources used in feeds for broilers, layers, and other animals.
Benefits:
High purity (>98%) with no heavy metal contamination
Particle sizes tailored for animal type (fine for chicks, coarse for adults)
High absorption in the digestive tract
Economical compared to other calcium sources
Supplying high-quality calcium carbonate is crucial for improving productivity in livestock and poultry farms. Feed-grade calcium carbonate is an efficient calcium source that supports growth and health.
Calcium carbonate is used in paper manufacturing as a filler to partially replace cellulose fibers. This mineral helps reduce pulp consumption while improving brightness, opacity, and surface strength of paper.
Benefits:
Increases brightness and whiteness
Reduces cellulose usage
Compatible with offset and digital printing
Lowers overall production costs
The use of calcium carbonate in the paper industry offers both economic and qualitative advantages, such as better printability and reduced raw material cost.
In the production of white bricks, mortar, and cement, high-whiteness calcium carbonate is used as an effective filler. It enhances the final color of the product, controls thermal expansion, reduces cracking, and increases durability.
Benefits:
Excellent whiteness and surface uniformity
Resistance to thermal shock
Reduces formulation cost
Improves workability of bricks and mortar
Using the right mesh size and purity level of calcium carbonate improves final product quality and overall production efficiency in the construction materials industry.
In powder detergents and industrial soaps, calcium carbonate serves as an active filler. It stabilizes powder structure, accelerates drying, reduces stickiness, and improves texture.
Benefits:
Lowers detergent production costs
Compatible with surfactants
Safe for fabric integrity
Uniform structure and excellent absorption
The use of calcium carbonate in detergent formulations provides a balanced combination of technical performance and economic efficiency.
