About Us
Hebei Hezhen Industrial Co., Ltd. specializes in high-quality kaolin powder, a key mineral material widely applied in ceramics, papermaking, coatings, rubber, and plastic industries. Adhering to the consistent quality philosophy of the company, the industrial-grade kaolin powder is developed to meet the strict requirements of global industrial customers, with outstanding performance in whiteness, purity, and processability.
Strict quality control runs through the entire production process of kaolin powder. The company selects high-quality kaolin ore from professional mining areas and conducts rigorous pre-inspection on raw materials to ensure the stability of ore quality. Advanced production equipment and mature processing technology are adopted, including crushing, grinding, classification, and purification, to realize automatic and refined production. Meanwhile, the company has passed ISO 9001 international quality management system certification, and the testing center is equipped with advanced instruments to conduct full-index detection on each batch of products, such as whiteness, particle size, moisture, and chemical composition, ensuring that every delivery meets the quality standards.
To meet the diverse needs of different customers, the company provides flexible MOQ (Minimum Order Quantity) customization services, suitable for both large enterprises with bulk procurement needs and small and medium-sized customers with small-batch trials. In terms of product application, the kaolin powder has excellent performance: in the ceramic industry, it can improve the plasticity and sintering performance of green bodies, making ceramic products more compact and smooth; in the papermaking industry, it serves as a filler and coating pigment to enhance paper whiteness and printability; in the coating industry, it can improve the covering power and weather resistance of coatings, reducing production costs.
FAQs
What is kaolin powder and what are its main uses?
Kaolin powder is a white, pasty mineral powder mainly composed of kaolinite minerals. Thanks to its excellent whiteness, chemical stability and adsorption properties, it is widely used in ceramics, paper, paints, coatings, plastics, rubber industries.
Which regions are the main exporters of kaolin powder?
The main exporting regions include the United States, Brazil, China, India and Australia. These regions dominate global production due to their abundant reserves and advanced processing technologies.
What quality standards should I pay attention to when importing kaolin powder?
Key parameters include: whiteness (≥85%), particle size distribution (D50<2μm for premium grades), moisture content (<1%), and chemical purity (low iron/titanium content). Certifications like ISO 9001 or industry-specific standards may also be required.
How is kaolin powder packaged for international transportation?
Usually, kaolin powder is packaged in 25kg or 50kg multi-layer paper bags. For large orders, bulk transportation (in bulk bags or bulk cargo vessels) is adopted. It is crucial to mark product specifications, batch numbers and safety labels (e.g., "non-hazardous goods") on the packages.
What are the common trade terms in kaolin powder trade?
Common trade terms include FOB (Free On Board), CIF (Cost, Insurance and Freight) and EXW (Ex Works). The selection depends on negotiations between buyers and sellers regarding transportation responsibilities and costs.
What documents are required for importing kaolin powder?
Required documents include commercial invoice, packing list, bill of lading (B/L), certificate of origin and quality inspection report. Some countries/regions may require additional permits (e.g., environmental compliance certificates).
What payment terms do kaolin powder suppliers commonly accept?
Suppliers commonly accept letters of credit (LC), telegraphic transfer (TT) or secure payment platforms (e.g., Alibaba Trade Assurance). The standard practice is to prepay 30% as a deposit, and the balance is paid before shipment.
Can kaolin powder be customized for specific industrial uses?
Yes, suppliers offer tailored grades based on client needs, such as:
Calcined kaolin (for high-temperature resistance in ceramics).
Surface-modified kaolin (for improved dispersion in coatings).
Ultra-fine kaolin (for premium paper or cosmetics).
