Product Introduction

Calcined Kaolin is a type of high-whiteness, ultra-fine particle size kaolin clay that has been calcined to enhance its properties. It is widely used in various industries as a cost-effective alternative to titanium dioxide, helping to improve whiteness, opacity, smoothness, and glossiness in paper and coatings. It is also valued for its high chemical inertness, which boosts the performance and longevity of products like paints, rubber, and cable insulation materials. With its excellent dispersion and chemical stability, calcined kaolin enhances the quality of end products while reducing production costs.

Product Features

• High Whiteness: The calcined kaolin clay has a whiteness of 91%, making it suitable for enhancing brightness in paper, coatings, and other applications.
• Ultra-Fine Particle Size: The fine particle size ensures excellent dispersion and surface coverage in various products.
• Cost-Effective Replacement for Titanium Dioxide: It can partially replace expensive titanium dioxide while maintaining or improving product performance.
• Improved Product Performance: Enhances the whiteness, smoothness, opacity, and glossiness of paper, paint, and coatings.
• Chemical Stability: High chemical inertness improves the durability of coatings and increases the resistance of rubber and other materials to aging and environmental degradation.

Product Specification

Product Application

• Paints and Coatings: As a titanium dioxide extender, calcined kaolin reduces costs in water-based and solvent-based paints, putty, and sealants. It enhances gloss, weather resistance, and color stability.
• Paper Coating: Improves brightness, glossiness, smoothness, and opacity in coated paper, art paper, newspapers, and thermal paper. Enhances ink absorption, printing adaptability, and gloss.
• Cable Insulation: Provides high volume resistance, good compatibility with base materials, and improved insulating properties for cable insulation materials.
• Rubber Industry: Enhances the chemical stability and aging resistance of rubber products, while improving air impermeability and reinforcing rubber strength.
• Plastics and Enamels: Used in plastic fillers, enamel formulations, and as a lightweight extender for reducing production costs while maintaining high performance.
