Dolomite Powder 800 Mesh
800 Mesh Dolomite Powder is a high-quality fine industrial dolomite filler, specially developed for medium and high-end premium product production. With fine uniform particle size, excellent fluidity and dispersion, it features standard CaO content (27–35% per TDS TDHX-Dolomite-2025-08) and high whiteness of 90-94. It can effectively improve the surface gloss and smoothness of finished products, with stable physical and chemical properties. It is widely used in high-gloss plastics, high-grade coatings and fine chemical industries

Product Performance & Advantages
800 mesh dolomite powder is processed through ultra-fine fine grinding and high-precision classification, with pass rate up to 92%-99.993%. The particles are uniform and delicate without agglomeration, with ultra-low moisture and stable chemical performance. Compared with medium mesh powder, it has better gloss enhancement and surface modification effects, making finished products smoother and more textured. It has strong compatibility with various resins and coatings, improving product weather resistance and anti-aging performance while maintaining high cost performance.
Application Scope
Suitable for high-grade modified plastics, high-gloss plastic finished products, precision functional masterbatch and premium rubber accessories. Widely used in high-gloss water-based coatings, industrial fine paints, precision printing inks and high-end adhesives and sealants. Also applicable for premium papermaking coating and high-end daily chemical auxiliary production.
Custom & Packaging
Full index customization supported. Multiple packaging specifications and OEM private label service. Price graded by customized parameters and product grades.

Frequently Asked Questions
What are the CaO and MgO contents of your dolomite powder?
Our dolomite standard TDHX-Dolomite-2025-08 specifies CaO 27–35%, MgO 22–30%, SiO₂ ≤8%, Fe₂O₃ ≤0.5% and whiteness 80–95. Individual grades sit inside that window; the TDS is available for download on this page. Tell us your target chemistry and we will confirm which grade matches.
Which industries use dolomite powder?
Glass and ceramics (CaO–MgO source), coatings and plastics (functional filler), construction (mortar and concrete), and environmental protection (flue gas desulphurisation).
Why is dolomite powder used in glass melting?
Dolomite supplies both CaO and MgO in one raw material, which lowers the melting temperature, aids refining, and improves the thermal and chemical durability of the finished glass.
Can dolomite powder be customised for my process?
Yes — mesh size from 200 to 2000 mesh, whiteness 80–95, and CaO/MgO ratios can all be adjusted. Free samples are available for bench testing.
