1002 Calcium Carbonate 2 Micron

Ultrafine performance filler for plastics, coatings, adhesives & more
Cemix 1002 Calcium Carbonate 2 Micron – Coated & Uncoated versions are engineered to deliver high performance, purity, and consistency across a broad range of applications. With an ultrafine particle size and reliable quality, these grades enhance mechanical strength, processing efficiency, and formulation flexibility in plastics, coatings, adhesives, and more.

Optimized particle size for enhanced performance:
With a D50 of 2 µm and D98 of 10 µm, Cemix 1002 offers excellent dispersion, uniform integration, and improved mechanical properties across plastic, adhesive, and coating systems.

High mechanical reinforcement & dimensional stability:
Both coated and uncoated grades contribute to increased stiffness, tensile strength, and impact resistance while helping minimize warping and shrinkage in end products.

Superior rheology and processing efficiency:
Ultrafine particle morphology enhances flow, reduces viscosity, and improves handling in liquid and solid formulations, boosting productivity and lowering energy use.

Customizable surface compatibility:
Available in stearic acid-coated form for hydrophobic applications and uncoated for water-based systems, providing tailored performance across a wide range of industrial needs.

Cost-efficient TiO₂ partial replacement:
Reduces titanium dioxide usage by up to 40% without compromising on whiteness, opacity, or surface finish—supporting more sustainable and economical formulations.

Reliable quality from high-purity marble:
Sourced from premium Uzbek marble and processed under strict quality control to ensure low impurity content and consistent batch-to-batch reliability.

Local production and secure packaging:
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.
