Major characteristics
Outstanding whiteness;excellent reducing power and covering power;excellent dispersibility in both of water-based and oil-based atmosphere; good weather resistance, heat resistance and light resistance and widely used.
Titanium dioxide occurs naturally in titanium ores such as titanium ore and rutile. Its molecular structure gives it high brightness and permeability, but it must first be chemically extracted and purified. More than 60 years ago, DuPont invented the chlorinated titanium dioxide production process, which has become the world's preferred technology because it can manufacture high-quality pigment products while reducing environmental emissions and Chemicalbook energy consumption compared to the old sulfuric acid process. Titanium dioxide (or TiO2) is the most widely used white pigment in industry, used in construction, industrial and automotive coatings; Plastics for furniture, electrical appliances, plastic tapes and plastic boxes; Paper for high-end magazines, brochures and films, as well as specialty products such as inks, rubber, leather and elastomers.

Titanium dioxide is an inorganic chemical pigment, the main component is titanium dioxide, non-toxic and tasteless.
Titanium dioxide is a white inorganic pigment with the best hiding power, whiteness and brightness, and is considered to be the best white pigment in the world.
Their chemical properties are relatively stable, and they do not react with most substances at room temperature.
They are an eco-friendly product and do not cause harm to the skin.
Titanium dioxide has the advantages of high purity, fine and uniform particles, strong refractive power, high decolorizing power, strong hiding power, low oil absorption, high water dispersibility, good whiteness, good gloss, and good durability.
The weather resistance, gloss retention and color reduction of rutile titanium dioxide are better than anatase titanium dioxide. For products with high weather resistance, only rutile titanium dioxide can be used. Anatase titanium dioxide is mainly used for products requiring low weather resistance and high whiteness.
Titanium dioxide is an important inorganic chemical pigment, mainly composed of titanium dioxide. The production process of all ATR series titanium dioxide is using sulfuric acid method. It has important applications in industries such as coatings, inks, papermaking, plastics and rubber, chemical fibers, ceramics, etc.
Its advantages over other types of titanium dioxide include:
1. Higher refractive index: Rutile titanium dioxide has a higher refractive index, which means it provides better hiding power and opacity.
2. Better weather resistance: Rutile titanium dioxide is resistant to weathering, which means it retains its color and properties for a longer time when exposed to sunlight, moisture, and other environmental factors.
3. Higher brightness and whiteness: Rutile titanium dioxide has a bright and white appearance, making it ideal for applications where a high degree of whiteness is required, such as in paper and coatings.
4. Superior tinting strength: Rutile titanium dioxide has a high tinting strength, which means it can produce a greater color intensity when mixed with other pigments or dyes.
5. Good stability and compatibility: Rutile titanium dioxide is chemically stable and compatible with other materials, including polymers, resins, and solvents, making it easy to incorporate into various formulations and manufacturing processes.
Titanium dioxide is commonly used in a wide range of industries and applications. Some of its primary applications include:
1. Pigment: Titanium dioxide is widely used as a white pigment in paints, coatings, plastics, inks, and paper, due to its opacity, brightness, and whiteness.
2. Sunscreen: Titanium dioxide is used as a UV-absorbing agent in sunscreens and other personal care products, as it helps to protect the skin from harmful UV rays.
3. Food additive: Titanium dioxide is used as a food additive in some countries, where it is used as a whitening agent, and as a thickening or anti-caking agent in certain foods.
4. Coatings and surface treatments: Titanium dioxide is used to improve the scratch resistance, durability, and other properties of coatings and surface treatments in various industrial applications.
5. Catalyst: Titanium dioxide is used as a catalyst in the chemical and petrochemical industries, for example, in the production of hydrogen from water using sunlight as a sustainable energy source.
6. Medical: Titanium dioxide is used in certain medical implants, such as dental implants and joint replacements, as it is biocompatible and has a low risk of allergic reactions.
7. Water treatment: Titanium dioxide is used as a photocatalyst in water treatment applications, where it helps to remove harmful contaminants and pollutants from water.
Titanium dioxide products are widely present in our daily activities, ranging from indoor latex paint, exterior wall coatings, car paint, air conditioning and washing machine casings, ceramic products, and even chewing gum, cosmetics, chemical fiber textiles, almost filling every aspect of our lives. They are mainly used in high-end industrial and daily products, and are a high-end white pigment. It can be said that without titanium dioxide, there would be no colorful material world around people.
