Calcium Carbonate-Functional additives that powers industries

In the vast world of industrial materials, very few substances are as versatile and widely used as Calcium Carbonate (CaCO₃). It is a an Additive that quietly powers some of the most essential sectors—paints, plastics, rubber, paper, cosmetics, pharmaceuticals, and more.

Whether it’s improving whiteness in paints, enhancing strength in polymers, reducing pulp usage in paper, or acting as a mild abrasive in toothpaste, Calcium Carbonate is the silent performer behind superior performance and cost-efficiency.

At 20 Microns Nano Minerals Ltd., we don’t just provide raw calcium carbonate. We engineer surface-modified, Nano-sized, and application-optimized CaCO₃ grades that are tailored to meet specific industrial needs—providing measurable improvements in process ability, aesthetics, mechanical properties, and regulatory compliance.

Calcium Carbonate is a naturally occurring compound composed of calcium, carbon, and oxygen (CaCO₃). It exists in various geological forms, including:

• Limestone
• Marble
• Chalk

There are two main industrial forms:

Nano Calcium Carbonate, an advanced form of PCC, is engineered for superior surface area and dispersion—especially beneficial in paints, plastics, rubber, and sealants.

• Boosts opacity and whiteness in decorative and industrial paints
• Improves viscosity, levelling, and film formation
• Offers Gloss and Matt Properties in paint and plastics

• Reduces TiO₂ usage without sacrificing coverage
• Helps control gloss, viscosity, and drying behaviour

We offer Nano-treated, hydrophilic/hydrophobic calcium carbonate to suit water- and solvent-based paints.

• Enhances rigidity, HDT (heat deflection temperature), and dimensional stability
• Reduces shrinkage and warpage
• Improves printability and impact strength in PP, PE, PVC, etc.

• Cost reduction without quality compromise
• Allows faster cooling in extrusion and injection moulding

Our surface-modified Nano CaCO₃ has tight particle size control, better dispersion, and excellent mechanical reinforcement.

• Works as a reinforcing filler
• Controls modulus, hardness, and abrasion resistance
• Reduces compound cost while maintaining elasticity

• Rubber hoses, tires, seals, gaskets, and conveyor belts

Our fine-grade CaCO₃ grades offer improved dispersion, filler-resin interaction, and longer tooling life during processing.

• Acts as both a filler and coating pigment
• Improves smoothness, brightness, and ink receptivity
• Reduces reliance on wood pulp and optical brighteners

• Face powders, foundations, and sunscreens (as texture agent and carrier)
• Toothpaste (as a mild abrasive)

• Biocompatible, non-irritating, and free from harmful additives

A masterbatch manufacturer in Gujarat was facing dispersion issues and lower tensile strength due to substandard CaCO₃.

We supplied a surface-modified Nano calcium carbonatetailored for LDPE.

Result: 35% improvement in pigment dispersion, 22% higher tensile strength, and a 15% cost saving by reducing resin load.

Calcium Carbonate is far more than a cost-saving filler—it’s a multifunctional Functional additive that can be engineered to unlock performance and value across industries.
