Product DescriptionProduct DescriptionWe supply premium-grade kaolin, a critical non-metallic mineral indispensable to ceramics, paper, paints & coatings, rubber, plastics and pharmaceuticals. Our range comprises both washed and calcined varieties, each sourced from carefully selected deposits and refined through state-of-the-art processing. The result is a product of exceptional purity, outstanding whiteness, ultra-fine particle size and superb dispersibility—delivering consistent performance across the most demanding applications.ApplicationsPapermaking: As both filler and coating pigment, kaolin boosts gloss, opacity and printability while cutting raw-material costs.Ceramics: An essential body ingredient, kaolin heightens fired strength, dimensional stability and whiteness, and markedly improves plasticity and green-body adhesion.Coatings: Thanks to its plate-like particles, kaolin delivers outstanding hiding power, high whiteness and uniform dispersion, making it ideal for all coating systems—especially premium architectural and industrial finishes.Cosmetics: Ultrafine kaolin refines texture, controls shine and enhances skin adhesion in powders, masks and creams.Other sectors: Reinforcing rubber and plastics, stabilizing pharmaceutical excipients, and serving as a functional additive across a broad range of specialty applications.Product FeaturesHigh Purity & Whiteness92–94 % ISO whiteness, low Fe/Ti content, guarantees brilliant end-products.Ultra-Fine & Narrow Particle SizeD90< 2 μm, plate-like morphology, ensures smooth surfaces and excellent coverage.Outstanding DispersionRapid de-agglomeration in water- or solvent-based systems; no flocculation, no sediment.Superior Chemical InertnessStable over pH 4–11, compatible with binders, pigments, and active ingredients.Low Abrasion & Low ResidueMinimal wear on wires, blades, or molds; < 0.01 % on 325 mesh for coating grades.Controlled RheologyAdjusts viscosity without gelling—ideal for high-solids coatings and high-speed paper machines.Environmentally Friendly & SafeNon-toxic, REACH-compliant, natural mineral with low carbon footprint.SpecificationTest ltem:Calcined KaolinTest indicatorsGE Brightness,%≥94.5%Oil absorbency, g/100g≥55%ph solids6-8Residue 325 mesh, %≤0.01size finer than 2 microns,%≥80Si0z content, %≥50Al20s content,%≥43Product specificationsGenerally, it is packed in 25kg/bag or 1000kg, lined with plastic film and woven bag outside.Packaging: 25kg/bag, 50kg/bag, 1000kg, etc.Storage and transportationStore in a clean, dry, well-ventilated warehouse; keep away from direct sunlight, moisture, dust, and any source of contamination.Safety instructionsDuring transit, shield the cargo from rain, moisture, and all contaminants to guarantee safe, intact delivery.Company ProfileQingdao Signal Technology Co.,Ltd Qingdao Signal Technology Co.,Ltd is a professional chemical trading company dedicated to providing high-quality products.

In the ceramic industry, the plasticity of washed kaolin makes it a key raw material for body molding; in the paper industry, it is used for paper coating to improve smoothness and printing adaptability.Q: What are the uses of calcined kaolin?A: Widely used in coatings, plastics, cables, electronic materials and other fields. In coatings, calcined kaolin can replace part of titanium dioxide to improve hiding power and weather resistance; in plastics, it can enhance product hardness and heat resistance.Q: Can washed kaolin and calcined kaolin be used interchangeably?A: It can be replaced in some scenarios, such as being used as filler to reduce costs; but in most cases it cannot be interchanged due to performance differences. For example, ceramic production must use the plasticity of washed kaolin; and high-performance coatings must use the functionality of calcined kaolin.
