Kaolin is a naturally occurring hydrated aluminum silicate widely utilized as a functional filler and pigment extender across global industries. This white clay mineral offers excellent opacity, chemical inertness, and softness, making it indispensable for high-volume manufacturing.

Available in various forms, including hydrous and calcined grades, it provides superior brightness and precise particle size distribution. Its low abrasion levels protect processing equipment while enhancing the mechanical strength and dimensional stability of end products.

As a cost-effective rheology modifier, Kaolin improves the flow properties and finish of coatings, ceramics, and adhesives. It serves as a vital component for reducing formulation costs while maintaining high performance in technical applications.

Kaolin

  • Paper Manufacturing: Acts as a filler and coating pigment to improve gloss, opacity, brightness, and printability in paper stocks.
  • Ceramics & Refractories: Provides plasticity and high melting strength for sanitary ware, tiles, porcelain, and electro-porcelain production.
  • Paints & Coatings: Functions as a functional extender to reduce Titanium Dioxideusage, control gloss levels, and improve film hardness.
  • Rubber Processing: Enhances stiffness, abrasion resistance, and tensile strength in mechanical rubber goods and cable insulation.
  • Plastics: Used as a reinforcing filler to improve surface finish and reduce shrinkage during the molding process.

Kaolin is generally classified as non-toxic but generates nuisance dust which may cause respiratory irritation upon prolonged exposure to high concentrations. Workers must utilize NIOSH-approved respirators (N95) and safety goggles to prevent inhalation and eye contact. Ensure adequate ventilation and dust extraction systems are active during handling.
