Molecular Weight: 79.87

Titanium dioxide is a white, odorless powder with high opacity and brightness. It is one of the most important white pigments, widely used for its excellent covering power and chemical stability.

Our company’s titanium dioxide is divided into two grades: food grade and industrial grade. It is available in two crystal types, anatase and rutile, and is produced via two production processes: the sulfate process and the chloride process.
All food-grade titanium dioxide adopts the anatase type. It features high purity and non-toxicity, and is suitable for high-standard safety scenarios such as food, cosmetics and pharmaceuticals.
Industrial-grade titanium dioxide is mainly the rutile type, which delivers excellent weather resistance and hiding power. It is widely used in industrial fields including coatings, plastics and papermaking. We also provide industrial-grade anatase titanium dioxide to meet diverse industrial application needs.
In terms of production processes, the sulfate process features low cost and high output, and can produce all conventional types of titanium dioxide. The chloride process produces products with higher purity, fewer impurities and better overall quality, and is mainly applied to the production of high-end industrial-grade and food-grade titanium dioxide.

Main Applications:

Used as a pigment in paints, coatings, plastics, paper, and cosmetics. Also applied in food coloring (E171) and as a photocatalyst in environmental applications.
