The plastic industry is the second largest user of Titanium Dioxide, accounting for about 18% of the world's total demand for titanium dioxidetitanium dioxide. It is the fastest growing field of titanium dioxide application in recent years, with an average annual growth rate of 6%. Among the more than 500 titanium dioxide brands worldwide, more than 50 are plastic specific.
An important branch of plastics and an important application field of titanium dioxide in plastics - UPVC profiles - have developed at an astonishing pace in China in the past decade, increasing at an average rate of 10%.
In 2008, the national production of profiles was 3.8 million tons, with approximately 135000 tons of rutile type TiO2 used. According to the annual increase of 10% in the national profile industry, in 2009, the demand for TiO2 in the national profile industry was about 150000 tons, while in 2010, it had reached 165000 tons.
Adding titanium dioxide to plastic can improve the heat resistance, light resistance, and weather resistance of plastic products, improve their physical and chemical properties, enhance their mechanical strength, and extend their service life.
Moreover, in recent years, with the continuous strengthening of people's awareness of environmental protection and energy conservation, the pace of replacing steel with plastics will be faster and faster in the future, and the proportion of plastic products in our lives will also be increasing.
The role of titanium dioxide in the plastic industry is mainly twofold. One is its basic use as a white pigment, providing a covering effect (white coloring); The second function is to block ultraviolet radiation, which is used as a UV screening agent to provide good weather resistance for plastic products used outdoors.
The titanium dioxide used in the production of ordinary plastics does not require weather resistance, but focuses more on the performance requirements of pigments.
For titanium dioxide used in plastics, it is required to have fine particles and good dispersion performance; Good heat resistance and light resistance, with no discoloration during heating and use of the finished product during plastic molding and processing.
Most plastics use titanium dioxide with a relatively fine particle size, typically ranging from 0.2 to 0.4 for coatings μ m. The particle size of titanium dioxide used in plastics is between 0.15 and 0.3 μ m. This can obtain a blue base phase, which has a masking effect on most resins with yellow phase or those prone to yellowing. Moreover, using titanium dioxide instead of lithopone can reduce the consumption of white pigments by 50% to 70%.
It is understood that domestic plastic products, especially high-end products, still mainly use imported chlorinated titanium dioxide. Chlorinated titanium dioxide not only has better surface properties such as whiteness than sulfuric ACID titanium dioxide, but also has unparalleled advantages in covering power, dispersibility, and processability, especially for outdoor UPVC plastic profile products and chlorinated rutile products.
However, due to the characteristics of plastic products, the considerations for selecting titanium dioxide powder are different from those for other coatings, inks, paints, etc. The main consideration should be based on the technical requirements of plastic products. For plastic specific products, it is necessary to carefully select titanium dioxide powder products suitable for their special purposes according to their product requirements, in order to avoid any impact on the performance of plastic products.
