Frequently Asked Questions
Coated dolomite offers superior polymer compatibility, better moisture resistance, improved processing efficiency, and enhanced mechanical properties in the final product.
The hydrophobic coating prevents moisture absorption, improves dispersion in PVC, enhances impact resistance, and provides better dimensional stability in PVC products.
While coated dolomite has a higher initial cost, it reduces processing time, lowers energy consumption, improves product quality, and reduces waste, making it more cost-effective overall.
Yes, coated dolomite can often replace more expensive fillers like talc or silica while maintaining or improving performance characteristics in many applications.
