ISO Calcined Kaolin 1250 Mesh for Rubber Filler

ISO Calcined kaolin 1250 mesh for rubber filler

Kaolin has a selection of applications which are grouped in three major locations: paper, ceramics and refractories.

Need is most in the manufacture of paper where it performs two individual capabilities- as a filler to improve printing traits and as a coating pigment to boost the surface area houses of the paper this sort of as the brightness, smoothness, gloss and ink receptivity and many others.

In the ceramics business the primary purpose of kaolin is to impart whiteness . Its key employs are in vitreous china sanitaryware, desk ware, wall tiles, electrical porcelain #8230

Kaolin is used in refractories exactly where it is valued for its alumina material.

Functionality mineral programs use kaolin as fillers in paint, rubber , plastics and adhesives and sealants and prescription drugs.

Other EPTant uses incEPT the manufacture of white cement and glass fibre.
