Frequently Asked Questions
Dolomite offers better mechanical strength, improved fire resistance, and enhanced durability in polymer applications. It's also more cost-effective for applications where maximum whiteness isn't critical.
Construction materials, ceramics, glass manufacturing, and rubber industries benefit most from dolomite powder due to its strength-enhancing properties and cost-effectiveness.
Dolomite powder improves tensile strength, impact resistance, and dimensional stability in polymers. It also reduces costs while maintaining product quality.
For paint applications, 400-600 mesh dolomite powder (15-25 microns) provides optimal coverage and finish quality. We offer sizes from 100 mesh (7-8 microns) to 1000 mesh (15 microns) to meet various application requirements.
