At NINGBO INNO PHARMCHEM CO.,LTD., we understand the critical role that specialized mineral fillers play in achieving superior product performance across various industries. Among these, calcined kaolin powder stands out for its exceptional properties and versatility. This processed form of kaolin clay, which has undergone high-temperature calcination, offers a unique combination of high whiteness, improved hardness, and altered particle morphology. These characteristics make it an invaluable component in formulations ranging from advanced coatings to durable ceramics and high-strength plastics.

The production of calcined kaolin involves heating raw kaolin clay to temperatures typically between 600°C and 1000°C. This thermal treatment effectively removes chemically bound water and transforms the kaolinite structure, resulting in a material with significantly enhanced properties. The resulting powder exhibits superior brightness and opacity compared to its hydrous counterpart. This makes it an ideal pigment extender, capable of partially replacing expensive pigments like titanium dioxide in paint formulations, thereby reducing costs while maintaining or even improving hiding power and whiteness.

In the realm of paints and coatings, the use of calcined kaolin powder from NINGBO INNO PHARMCHEM CO.,LTD. offers several advantages. Its fine particle size and high whiteness contribute to the smooth texture and excellent coverage of paints. Furthermore, the improved mechanical properties imparted by calcined kaolin can enhance the durability and scratch resistance of the coating. The thermal stability of this material also makes it suitable for high-temperature applications within the coatings industry.

The ceramics sector significantly benefits from the inclusion of calcined kaolin. Its inherent whiteness is crucial for producing bright, aesthetically pleasing ceramic products. Moreover, the calcined nature means it is already thermally stable, thus minimizing shrinkage during firing and contributing to the overall structural integrity and fine surface finish of ceramic items, from tiles to sanitary ware. The purchase of calcined kaolin for these applications ensures consistent quality and performance.

For the plastics and rubber industries, calcined kaolin serves as an effective reinforcing filler. By incorporating this fine powder into polymer matrices, manufacturers can achieve significant improvements in tensile strength, modulus, and impact resistance. Its properties also contribute to better dimensional stability and surface finish in molded plastic products. The ability to buy calcined kaolin powder tailored for these specific needs is a testament to its adaptability.

At NINGBO INNO PHARMCHEM CO.,LTD., we are committed to providing high-quality calcined kaolin that meets the stringent demands of modern industrial processes. Our dedication to quality assurance ensures that clients receive a product that consistently delivers exceptional results, whether for cost-effective pigment extension in paints, enhancing the aesthetic and structural properties of ceramics, or bolstering the performance of plastics and rubber.
