Titanium dioxide, commonly abbreviated as TiO₂, is one of the most widely used white pigments in the world due to its superior opacity, brightness, and UV resistance. In industrial applications, titanium dioxide is not a one-size-fits-all material. Instead, it is produced and refined into various grades, each designed for specific end uses. These different grades of titanium dioxide vary in crystal structure, surface treatment, particle size, and dispersion properties, which in turn determine their suitability for different industries such as coatings, plastics, paper, ceramics, and rubber.

Titanium Dioxide Grades in the Coating Industry

The coatings industry demands high-performance titanium dioxide grades that offer excellent opacity, brightness, and durability. Rutile-grade titanium dioxide is particularly favored in this field. Products like Hebei Caiqing Material Technology Co., Ltd.’s CR-930 series are examples of high-end rutile titanium dioxide designed for both interior and exterior coatings. These grades undergo specialized surface treatments to enhance dispersion and resistance to environmental degradation. In paints and coatings, such grades provide strong coverage with minimal pigment volume concentration, making them cost-effective while delivering lasting performance. High-quality coating-grade TiO₂ also resists yellowing and chalking, ensuring a long lifespan for architectural and industrial coatings.

Paper and Printing Applications of Titanium Dioxide Grades

In the paper and printing industries, titanium dioxide grades are selected based on their ability to improve brightness, opacity, and printability. Here, anatase-grade titanium dioxide is commonly used. While it offers slightly lower durability compared to rutile, anatase TiO₂ provides excellent whiteness and smooth dispersion, making it ideal for paper coatings, specialty papers, and printing inks. Products such as the BA01-01 and CA100 series from Caiqing Technology exemplify this application-focused approach. These grades are engineered to integrate seamlessly into aqueous formulations used in paper processing, contributing to enhanced sheet smoothness, whiteness, and ink receptivity.

Titanium Dioxide in Plastic and Rubber Applications

In plastics and rubber manufacturing, titanium dioxide grades are tailored to meet the demands of dispersion, heat stability, and UV protection. Rutile TiO₂ grades are often chosen for outdoor plastics and automotive components due to their superior lightfastness and resistance to UV degradation. In contrast, other formulations are designed for indoor plastic products, where surface gloss and whiteness are more important than long-term durability. Rubber applications, such as tires and seals, require grades with excellent reinforcing properties and even particle distribution, ensuring product uniformity and resistance to wear.

Specialty Titanium Dioxide Grades for Ceramics and Other Industries  

Specialty titanium dioxide grades are also developed for use in ceramics, glass, and even certain food and pharmaceutical products. These applications often demand high purity and specific physical characteristics. In ceramics, for instance, TiO₂ acts as an opacifier, enhancing color and surface texture. The grade used must be finely milled, with consistent particle size to ensure even firing results and surface finish. While Caiqing Technology’s main focus lies in industrial-grade titanium dioxide, the adaptability of their product lines makes them suitable for a wide range of specialty uses with customized formulations.

Meeting Global Demand with Tailored Titanium Dioxide Grades

Hebei Caiqing Material Technology Co., Ltd. has built a strong global reputation by offering a diverse portfolio of titanium dioxide grades tailored to meet the specific needs of various industries. With an annual output capacity of 100,000 tons and a customer base spanning Southeast Asia, Africa, the Middle East, India, and Russia, Caiqing Technology is capable of providing consistent, high-performance TiO₂ solutions on an international scale. Their dedication to technological advancement and product customization ensures that each grade of titanium dioxide meets the functional and economic needs of its intended application.

In conclusion, the classification of titanium dioxide into different grades is essential for its effective use across industries. From high-durability rutile grades for coatings to finely dispersed anatase grades for paper and plastics, each type plays a critical role in delivering optimal results. Caiqing Technology continues to lead in the development and global distribution of these vital materials, reinforcing the importance of matching the right titanium dioxide grade to the right application.
