A fine white hydrous aluminium silicate clay valued for its exceptional brightness, plasticity, and chemical purity across ceramics, paper, pharmaceuticals, and specialty applications.
Kaolin, commonly known as china clay, is a soft white clay mineral composed primarily of kaolinite (Al₂Si₂O₅(OH)₄). Its naturally high brightness, fine particle size, and chemical inertness make it one of the most widely used industrial minerals worldwide.
The unique plate-like particle structure of kaolin delivers exceptional covering power in coatings, smooth surface finishes in paper, and controlled rheology in ceramic slips. Its low abrasiveness and high whiteness set it apart from other clay minerals.
A.N. Enterprises supplies processed kaolin across a broad mesh range from 200 to 1250, with controlled brightness and particle size distribution tailored to each application sector.
Comprehensive chemical and physical parameters ensuring consistent quality for all target applications.
SiO₂ content reflecting the kaolinite mineral structure, contributing to the refractory behaviour and chemical stability of the clay.
High Al₂O₃ content is the hallmark of quality kaolin, providing refractoriness, whiteness, and suitability for ceramic and paper applications.
Fe₂O₃ maintained at minimal levels to preserve the natural high brightness and prevent discolouration in fired ceramics and coated papers.
Slightly acidic to neutral pH ensures compatibility with a broad range of formulations in coatings, ceramics, rubber, and pharmaceutical applications.
Median particle size controlled across grades to suit specific applications, from ultra-fine coating grades to coarser filler grades for rubber and ceramics.
Oil absorption values indicating the pigment loading capacity, critical for optimising binder demand in paints, coatings, and rubber compounds.
From fine ceramics to pharmaceutical formulations, kaolin serves as a foundational material across a remarkably diverse range of industries.
Kaolin is the backbone of ceramic manufacturing. It provides plasticity for forming, whiteness in fired bodies, and contributes to the mullite phase that gives ceramics their mechanical strength. In glazes, kaolin acts as a suspension agent and provides alumina to the melt, controlling glaze flow and preventing crazing.
The paper industry is one of the largest consumers of kaolin. As a coating pigment, kaolin delivers superior brightness, improved printability, and a smooth surface finish. As a filler, it improves opacity, reduces ink strike-through, and provides a cost-effective way to enhance sheet properties while reducing fibre content.
In rubber compounding, kaolin serves as a semi-reinforcing filler that improves tensile strength, abrasion resistance, and dimensional stability. Calcined grades offer enhanced reinforcement properties. The plate-like particle morphology provides a unique balance of stiffness and flexibility in the final compound.
Kaolin functions as an extender pigment in paints and coatings, reducing the demand for expensive titanium dioxide while maintaining acceptable opacity and coverage. Its plate-like particles improve film integrity, brushability, and sag resistance, making it a preferred choice for both interior and exterior coatings.
Pharma-grade kaolin serves as an excipient and diluent in tablet formulations, a carrier for active pharmaceutical ingredients, and has historical use in anti-diarrheal preparations. Its chemical purity, controlled particle size, and absence of heavy metals make it suitable for oral and topical pharmaceutical products.
Kaolin is a staple ingredient in cosmetic formulations, particularly in face masks, powders, and cleansing products. Its natural absorbency draws out excess oils and impurities from skin, while its fine texture provides a smooth, silky application. The gentle nature of kaolin makes it suitable for sensitive skin formulations.
In wire and cable manufacturing, kaolin acts as a functional filler in PVC and rubber insulation compounds. It improves electrical resistance, enhances mechanical properties of the insulation jacket, and provides fire-retardant characteristics. Its low moisture absorption ensures long-term reliability of cable insulation in demanding environments.
Rigorous testing protocols ensure every batch of kaolin meets the exacting requirements of your applications.
ISO brightness measurements on every batch ensure values remain within the 80–90% specification range. Spectrophotometric analysis confirms colour consistency critical for paper coating and ceramic applications.
Laser diffraction analysis verifies d50 values and full particle size distribution curves. Tight control of fines and oversize fractions ensures predictable performance in coating, filling, and compounding operations.
XRF analysis confirms Fe₂O₃ content remains below 1% in every shipment. Low iron levels protect against discolouration in fired ceramics, maintain paper brightness, and ensure suitability for pharmaceutical and cosmetic grades.
Complete oxide analysis including SiO₂, Al₂O₃, Fe₂O₃, TiO₂, CaO, MgO, Na₂O, and K₂O is performed on every batch. Consistent chemical composition ensures reproducible results in your process.
Oil absorption values and pH are monitored to ensure formulation compatibility. These physical properties directly impact binder demand in coatings, rheology in ceramic slips, and dispersion behaviour in rubber compounds.
Complete traceability from source deposit through processing and dispatch. Every shipment includes a Certificate of Analysis with full chemical, physical, and brightness test results for your quality records.
