Rutile titanium dioxide is an inorganic white pigment with high refractive index, excellent chemical stability and light resistance. Compared with anatase titanium dioxide, rutile titanium dioxide has higher performance in weather resistance, light scattering and chemical stability, so it has gradually become the mainstream choice in industrial applications. Especially in the fields of coatings, plastics, paper making, ink and so on, rutile titanium dioxide is widely favored because of its excellent optical properties and excellent durability. With the increasing demand for high-performance materials, the market demand for rutile titanium dioxide shows a steady upward trend.

Basic Characteristics of Rutile Titanium Dioxide

Rutile titanium dioxide shows some unique physical and chemical characteristics because its crystal structure is different from that of anatase:

High refractive index: the refractive index of rutile titanium dioxide reaches about 2.7, which is much higher than other pigment materials. This characteristic makes it excellent in light scattering and hiding power, which can effectively cover the surface defects of products and improve whiteness and brightness.

Excellent weather resistance: Rutile titanium dioxide has high stability to ultraviolet radiation and is not prone to photochemical reaction, so it is not easy to fade in outdoor and high ultraviolet environment, and is suitable for products exposed to sunlight for a long time.

Chemical resistance: Rutile titanium dioxide pigment shows excellent stability in acid, alkali and other environments, so it can ensure that the performance of the pigment is not affected when used in various harsh environments.

Low water absorption: Compared with anatase pigment, rutile titanium dioxide has low water absorption, which can ensure the durability and stability of the product, especially in the environment with large humidity change.

These characteristics make tio2 rutile have an irreplaceable position in many industrial applications and become one of the important basic materials in modern industry.

Main Application Fields of Rutile Titanium Dioxide

Coating Industry

In the coating industry, rutile titanium dioxide is widely used in architectural coatings, automotive coatings, industrial coatings and other fields. Its high hiding power and excellent light stability make the coating have lasting luster and color stability after coating, and it is not easy to fade. Especially in exterior wall coatings, rutile titanium dioxide can effectively resist the erosion of ultraviolet rays and ensure the aesthetics and durability of buildings.

Plastics Industry

Plastic industry is another major application field of tio2 rutile. Adding rutile titanium dioxide into plastics can not only increase the whiteness and opacity of plastic products, but also provide excellent anti-ultraviolet function. The application of rutile titanium dioxide in plastics includes PVC, PE, PP and other plastic materials, which are used to produce pipes, films, containers, household appliance shells and other products.

Paper Industry

In the papermaking industry, rutile titanium dioxide is widely used in coated paper and art paper because of its excellent whiteness, brightness and hiding power, which makes the paper have higher brightness and opacity. In addition, rutile titanium dioxide also has certain oil absorption performance in paper production, which can reduce the adsorption of printing ink and improve the printing effect.

Ink Industry

The application of rutile titanium dioxide pigment in ink industry is mainly reflected in high-quality white ink. It can provide good whiteness and opacity for ink, and make the printing effect clearer and more lasting. Its excellent dispersibility and chemical stability are also helpful to improve the fluidity and uniformity of ink, and it is suitable for various printing types.

In addition to the above main applications, rutile titanium dioxide is also used in ceramics, textiles, rubber, cosmetics and other fields. For example, in cosmetics, rutile titanium dioxide is often used as a sunscreen to help products resist ultraviolet damage and protect skin from damage. In the ceramic industry, its heat resistance and chemical resistance make it one of the high-quality glaze components.
