Kaolin Powder Plastics Paints Glazes

Premium Kaolin Powder for Industrial & Cosmetic Applications

Kaolin, also known as China clay (CAS No. 1332-58-7), is a naturally occurring, versatile hydrated aluminum silicate mineral. Its fine particle size, chemical inertness, and bright white color make it an indispensable raw material across a diverse range of industries, including ceramics, paper, paints, plastics, rubber, and cosmetics. At Huabang Mica, we supply high-purity kaolin powder tailored to meet the exacting demands of both industrial and cosmetic applications. Our rigorous quality control ensures consistent particle size distribution and chemical composition, delivering reliable performance batch after batch for critical manufacturing processes.

Types of Kaolin: Metakaolin, Washed, and Calcined

Super-Fine Active Metakaolin for High-Performance Concrete

In the realm of cement concrete, super-fine active metakaolin stands out as a high-performance supplementary cementitious material (SCM). Its extremely fine particle size and high pozzolanic reactivity enable it to react with calcium hydroxide released during cement hydration. This reaction forms additional calcium silicate hydrate (C-S-H) gels, significantly enhancing the concrete's density, strength, and durability. The use of metakaolin improves resistance to chemical attacks such as sulfate and chloride ingress, reduces permeability, and mitigates alkali-silica reaction (ASR). These properties make it ideal for high-strength, long-lasting construction projects, including marine structures, bridges, and high-rise buildings, while contributing to a lower carbon footprint by partially replacing ordinary Portland cement.

Washed Kaolin for Paper, Paints, and Coatings

Washed kaolin is a cornerstone in the paper industry. After a thorough washing process to remove impurities like quartz and mica, it offers excellent opacity, brightness, and printability. As a filler and coating pigment, it enhances the paper's surface smoothness, allowing for sharp and high-quality printing results. Beyond paper, washed kaolin serves as a functional extender in paints and coatings, where it improves scrub resistance, hiding power, and suspension properties while reducing formulation costs by extending expensive pigments like titanium dioxide (TiO2). Its controlled particle size and high brightness ensure consistent color and gloss in every application.

Calcined Kaolin for Ceramics, Refractories & Plastics

Calcined kaolin is a key ingredient in ceramics and refractories. The calcination process alters its structure through controlled thermal treatment, increasing its whiteness, hardness, and improving its thermal stability. In ceramic bodies, it is used to adjust the firing temperature and shrinkage rate, ensuring consistent, high-quality ceramic products with fine textures and appealing finishes. In plastics and rubber, calcined kaolin acts as a high-performance reinforcing filler, providing dimensional stability, electrical insulation, and improved surface finish. In refractory applications, its high-temperature resistance makes it an ideal component for kiln furniture, furnace linings, and investment casting shells.

Detailed Product Specifications & Parameters

Our standard kaolin powder is rigorously tested to ensure it meets the highest industry standards for purity and consistency. We offer two primary grades: Cosmetics Grade, which is micronized, purified, and sanitized for safe use in facial masks, powders, soaps, and personal care formulations; and Industrial Grade, optimized for high-performance applications in construction, paper, paint, and polymer compounding. Our flexible packaging and low minimum order quantity (MOQ) make it easy to procure for both trial runs and large-scale production.
