1001 CALCIUM CARBONATE 1 MICRON

High-purity GCC for industrial applications requiring coarser particle size
Cemix 1001 Calcium Carbonate 1 Micron is engineered to deliver superior structural integrity, cost efficiency, and versatile performance across diverse industries. With a controlled coarse particle distribution (D50 of 1 μm, D98 of 4 μm) and high chemical purity, this grade ensures enhanced mechanical reinforcement, optimal bulk density, and reliable formulation stability in construction materials, polymers, coatings, adhesives, and beyond.

Unmatched whiteness purity
With brilliant whiteness of 96–98% from our premium marble deposits, our product ensures a clean, bright appearance ideal for sensitive applications.

Optimized particle size for performance
Ultrafine particle size D50 1 μm, D98 4 μm enables smooth dispersion and excellent integration into polymer, coatings, and adhesive formulations.

Improved processing efficiency
Low oil absorption reduces viscosity in formulations, improving processability and reducing binder demand.

High thermal stability
Maintains performance even in high-temperature processing, making it suitable for plastics and rubber applications.

Excellent dispersion in water-based and solvent-based systems 
Ideal for coatings, paints, and adhesives that require uniform blending.

TiO₂ replacement potential  
Provides high brightness and opacity, allowing for partial replacement of expensive titanium dioxide in coatings, plastics, and paper.

Cost-effective functional Filler
Improves mechanical strength and dimensional stability while enhancing opacity, coverage, and bulk in polymers, adhesives, and coatings.

Local production and reliable package
Manufactured in Uzbekistan for stable supply and lower logistics costs. Supplied in durable, moisture-resistant 25 kg PE bags for safe storage and handling. Also possible to supply in Big Bags.
