For Sales Inquiry

In modern industrial manufacturing, minerals are no longer used merely as cheap extenders to reduce volume costs. Instead, materials like high-whiteness calcite and coated calcium carbonates are engineered as functional additives. They enhance structural, optical, and physical properties in compounding. As a leading white calcium carbonate powder supplier, Labdhi Ventures provides high-brightness, precision-milled mineral fillers optimized for the paint, plastic, rubber, and masterbatch industries.

Our calcite and limestone deposits are renowned for high chemical purity (low iron and heavy metal content) and maximum brightness. These characteristics are critical for plastic compounding and paint formulation, ensuring bright final colors, excellent dispersion, and chemical resistance.

Functional Fillers for Paint and Plastics

We process and supply premium mineral fillers tailored to the viscosity, dispersion, and opacity requirements of plastic processors and paint manufacturers:

Precision Milling and Quality Consistency

The key to successful plastic compounding and paint blending is particle consistency. Standard grids range from 2 microns up to 20 microns (300 mesh to 1250 mesh), backed by advanced grinding circuits that maintain tight size margins. Our stearic acid-coated grades offer excellent surface wetting, reducing polymer viscosity and mixer wear.

We supply bulk containers and customized packing options to processing centers throughout Rajasthan, Gujarat, and Ahmedabad. Our supply chain guarantees on-time delivery of premium mineral filler supplier materials directly to plastic extruders, profile extrusion plants, and paint mills.

Frequently Asked Questions

What is the function of calcite powder in plastic and polymer processing?
Calcite powder increases polymer stiffness, stabilizes melt flow rates, controls shrinkage, and enhances mechanical impact resistance. High-purity calcite also improves the thermal conductivity of the melt, reducing molding cycle times.
How does calcite powder benefit paint formulations?
It acts as a cost-effective extender that enhances opacity, improves scrubbing resistance, controls gloss levels, and ensures stability in both water-based emulsions and solvent-based paints.
Do you supply surface-treated (coated) calcium carbonate powder?
Yes. We supply stearic acid-coated calcite powder. Coating makes the powder hydrophobic, allowing it to disperse smoothly inside polyolefin plastics (like PP and PE) without agglomerating.
What particle sizes are available for industrial filler applications?
We supply powders ranging from 300 mesh (approx. 50 microns) to ultra-fine 1250 mesh (approx. 10 microns) and sub-micron grades, depending on the extrusion or coating process requirements.
