What Is Whiting Chalk Powder? Properties, Grades & Industrial Applications
Whiting Chalk Powder is one of the most widely used industrial minerals across paints, plastics, rubber, paper, construction, and several other manufacturing sectors. Known for its excellent whiteness, smooth texture, and superior dispersion, this mineral acts as an economical and highly effective filler material.
In this blog, we’ll explore what Whiting Chalk Powder is, its properties, available grades, and how different industries use it in their formulations.
What Is Whiting Chalk Powder?
It is a naturally occurring form of calcium carbonate (CaCO₃). It is derived from soft white chalk mineral deposits that are crushed, ground, and processed to achieve different mesh sizes and purity levels.
Because of its non-toxic, chemically stable, and versatile nature, Whiting Powder is preferred by manufacturers who need a consistent and cost-effective filler solution.
Key Properties of Whiting Chalk Powder
Whiting Powder is valued for its wide range of physical and chemical properties, such as:
1. Soft Texture
Easy to mix and offers smoothness in final products.
2. Good Dispersion
Blends uniformly with liquids and powders without clumping.
3. Chemical Stability
Does not react with most industrial chemicals, binders, or additives.
4. Good Opacity
Improves coverage in paints and coatings.
5. Cost-Effective Filler
Replaces expensive raw materials, helping manufacturers reduce production costs.
Common Grades of Whiting Chalk Powder
Different industries require different mesh sizes and purity levels. The most common grades include:
• 200 Mesh
Used in basic putty, distemper, and construction applications.
• 300 Mesh
Ideal for paints, wall putty, primers, and plastic compounds.
• 400 Mesh and Above
Used where high purity and smooth finish are required—rubber, cosmetics, high-quality coatings.
• Lumps & Granules
For special industrial applications before further grinding.
Choosing the right grade depends on your application, desired smoothness, and required whiteness.
