Application of Titanium Dioxide in Plastic ,Paper and Rubber:

PLASTIC: the application of Titanium Dioxide in plastic products,in addition to its high hiding power ,high tinting power,high pigment properies,can also improve the heat resistance, light resistance and weather resistance of plastic products,protect plastic products from UV light,and improve the mechanical and electrical properties of plastic products.

PAPERMAKING:Paper made with Titanium Dioxide has good whitness,high strength,good gloss,thinness and smoothness,and is not permeable when printed.Under the same conditions,its opacity is 10 times higher than that of calcium carbonate and talcum power,and its weight can be reduced by 15% to 30% .therefore,titanium dioxide must be used for decorative paper,Bilble paper and banknotes.

RUBBER:Titanium Dioxide is used as a colorant in the rubber industry,and also has the functions of reinforcement,anti-aging and filling. it is mainly used in automobile tires,rubber shoes,rubber floors,gloves,sports equipment,etc.,and is generally anatase type.

Characteristics of Titanium Dioxide for Plastics 

Light scattering and color presentation: Titanium dioxide is often used as a white pigment in polymers. Because of its high scattering ability, it can effectively scatter visible light, giving plastic products a white appearance and excellent opacity. Its light scattering characteristics depend on the crystal structure and particle size distribution, and the appropriate particle size interacts with the wavelength of visible light to achieve efficient scattering and present an ideal white effect.

Ultraviolet absorption and protection: Titanium dioxide is a light-responsive material, which can absorb ultraviolet rays and convert them into heat energy to protect polymers from degradation. Outdoor plastic products are easy to be eroded by ultraviolet rays. After adding titanium dioxide, they can resist damage, prolong service life and maintain good performance and appearance.

Chemical and thermal stability: Titanium dioxide is chemically stable, chemically inert and insoluble in common polymers. Under the condition of high temperature and high pressure processing of plastic products, it can still remain stable, without chemical reaction, decomposition and volatilization, which ensures the stability of the performance in products and helps high-quality production.

Crystal Form and Application Difference of Titanium Dioxide 

Anatase and Rutile tio2：Titanium dioxide mainly has two crystal forms: anatase and Rutile. There are some differences in structure and properties between the two crystals, which leads to different performances in plastic applications. Anatase titanium dioxide has high photocatalytic activity, which may have certain application value in some specific application scenarios, such as photocatalytic degradation of organic pollutants. However, in the plastic industry, rutile titanium dioxide is more popular.

Advantages of Rutile: Rutile titanium dioxide has obvious advantages in plastic application. It has higher light scattering efficiency, can make plastic products appear whiter and brighter, and has higher opacity. At the same time, rutile titanium dioxide has stronger chemical stability and is less prone to photocatalytic reaction in complex environment, especially under ultraviolet irradiation, thus avoiding the catalytic degradation of polymers and ensuring the long-term stability and durability of plastic products.

Packaging industry: In the field of plastic packaging, titanium dioxide is widely used. Like food packaging, titanium dioxide with good dispersibility and stability is needed to ensure that the packaging is white and transparent and does not pollute the food; Cosmetic packaging uses the high whiteness and opacity of titanium dioxide to enhance the texture and aesthetics and attract consumers.

Construction industry: Titanium dioxide is widely used in plastic products for construction. After adding titanium dioxide powder to plastic doors and windows, the appearance is beautiful and the weather resistance is enhanced, and it is not easy to fade and deform after long-term sun exposure; Adding titanium dioxide to plastic pipes can improve corrosion resistance and durability and ensure normal use.

Application of Titanium Dioxide in Construction Industry 

Plastic doors and windows: Plastic doors and windows are widely used in buildings, and titanium dioxide has significantly improved their performance. On the one hand, titanium dioxide gives plastic doors and windows a beautiful white appearance, which meets the public's aesthetic demand for architectural appearance. On the other hand, its ultraviolet resistance and weather resistance make plastic doors and windows not easy to fade and deform in the environment of long-term wind, sun, rain and snow erosion, prolong service life and reduce building maintenance cost.

Plastic pipes: Plastic pipes for buildings, such as water supply and drainage pipes, should have good corrosion resistance and durability. After adding titanium dioxide powder, the chemical stability of plastic pipes is enhanced, which can resist the corrosion of chemicals in water, ensure that there will be no problems such as cracking and leakage during long-term use, and ensure the normal operation of building water supply and drainage systems.

Exterior wall decorative board: Exterior wall decorative board is an important part of the building facade, which requires aesthetics and durability. Titanium dioxide powder can make decorative boards show rich colors and meet the design requirements of different architectural styles. At the same time, its excellent weatherability enables the decorative board to keep bright colors and smooth surfaces under various bad weather conditions, and enhances the overall aesthetics and value of the building.
