Coated Dolomite Powder

Minimum Order Quantity: 5 Tonne

Our premium Coated Dolomite Powder undergoes a specialized surface treatment using high-grade fatty acids (stearic acid) designed specifically for advanced polymer applications. Natural dolomite is inherently hydrophilic (absorbs moisture), which can cause catastrophic blistering or structural weakness in high-heat plastic and rubber extrusion. Our intensive coating process transforms the powder into a hydrophobic (water-repelling) master material, aggressively locking out atmospheric moisture. The fatty acid coating drastically reduces the surface tension of the dolomite particles, promoting incredible compatibility and rapid dispersion within complex organic polymer matrices. This allows manufacturers to utilize much higher filler loading limits without compromising the mechanical integrity, tensile strength, or elongation properties of the final product. It virtually eliminates die build-up and enhances the melt flow index during processing. Coated Dolomite Powder by Raviraj Minerals is highly recommended for high-end consumer plastics, PVC pipes, cables, and synthetic rubber compounding. By switching to our coated variant, manufacturers gain superior dimensional stability, an impeccably smooth surface finish, and significant cost savings through optimized filler loading ratios.
