Sree Sai Mineral Industries produces calcined kaolin through controlled thermal processing of high-purity washed kaolin, achieving a level of brightness, opacity and abrasion resistance that raw and hydrous grades cannot match.
Our calcined kaolin is widely used as a functional filler and opacifier in high-opacity coatings, engineering plastics and specialty rubber compounds, backed by an in-house quality laboratory and a Certificate of Analysis with every batch.
Controlled thermal calcination delivers brightness values exceeding standard hydrous grades.
Increased refractive index and air-void structure boost hiding power.
Hardened particle structure after calcination improves wear and abrasion resistance.
Batch-to-batch uniformity verified in our in-house QC lab.
Sree Sai CalcinePure is a high-brightness calcined kaolin manufactured through controlled thermal processing. It delivers exceptional opacity, whiteness and durability for demanding coating, plastic and rubber applications.
