1003 CALCIUM CARBONATE 3 MICRON
High-Purity GCC for Enhanced Performance & Versatile Industrial Use
Cemix 1003 Calcium Carbonate 3 Micron – Uncoated delivers exceptional performance, versatility, and cost savings.
Optimized Particle size Distribution for superior performance: With a D50 of 3 μm and D98 of 13 μm, Cemix 1003 offers a balanced particle size distribution (PSD), ensuring excellent dispersion, smooth processing, and enhanced mechanical properties. Its fine yet stable granulometry makes it a highly effective functional filler across multiple industries.
Enhanced mechanical strength & dimensional stability: Cemix 1003 significantly improves stiffness, tensile strength, and impact resistance in plastics, coatings, and adhesives. By reinforcing polymer matrices, it minimizes shrinkage and enhances structural integrity, making it ideal for injection molding, extrusion, and composite materials.
Improved rheology & processing efficiency: The finely controlled PSD of Cemix 1003 optimizes viscosity, flowability, and workability in liquid and solid formulations. This enables easier processing, reduced energy consumption, and higher production efficiency in applications like paints, sealants, and adhesives.
High brightness & excellent optical properties: With high whiteness and controlled particle morphology, Cemix 1003 enhances opacity and brightness in coatings, paints, and polymer applications. This results in better UV resistance, improved color consistency, and superior surface smoothness.
Cost-effective & sustainable partial TiO₂ replacement: Cemix 1003 provides a cost-efficient alternative to titanium dioxide (TiO₂) and helps to reduce its usage by up to 40% in paints, coatings, and plastics. It offers similar optical and functional properties, reducing formulation costs while maintaining high performance.
