High brightness kaolin filler for rubber, plastics, paper, paints, and more.
A commitment to quality at every step, managing raw purity from our mine to your refined solution.
Kaolin mines at Uttaradit
Our journey begins in the mineral-rich hills of Uttaradit, where Darson operates its own private mining concession.
By controlling the source, we bypass third-party inconsistencies, carefully selecting only the purest raw kaolin seams. This direct oversight ensures that every batch starts with a foundation of uncompromised quality.

Kaolin Reserve
Located at our 38,400 sqm facility, we process raw materials using advanced Dry Grinding & Ball Mill technology.
Crucially, we utilize high-grade alumina balls as our grinding medium. Unlike steel balls, alumina prevents iron contamination (rust), maintaining consistent brightness and purity across all product grades.
