About White Chalk Powder

By using the advanced technology we produce our White Chalk Powder that is also known as calcium carbonate which is non-combustible in nature. This odorless white powder naturally occurs in the minerals of aragonite, calcite, limestone, and marble. Our high quality of White Chalk Powder is free from toxic materials that make it pure. Apart from this, our valued customers can avail the powder in an airtight packet that avoids wastage of the product while transportation from one place to another.

Exceptional Whiteness and Purity

This White Chalk Powder delivers a minimum of 95% whiteness with a purity level between 9899%, ensuring clean applications in industries ranging from paint to pharmaceuticals. Its finely micronized form guarantees a uniform dispersion, making it an ideal pigment and filler for high-quality end products.

Safe and Stable Industrial Solution

Our chalk powder is entirely non-toxic and non-hazardous, with heavy metals well within permissible limits. The powders insolubility in water and non-flammable nature offer stability in diverse environments, while its alkaline pH (9.09.5) supports compatibility with numerous formulations.
