Secondly, TiO2 acts as a UV stabilizer in plastics. When exposed to sunlight, plastics can degrade over time due to the harmful effects of ultraviolet rays. However, TiO2 has the ability to absorb UV radiation and convert it into heat, preventing the degradation of the plastic material However, TiO2 has the ability to absorb UV radiation and convert it into heat, preventing the degradation of the plastic material However, TiO2 has the ability to absorb UV radiation and convert it into heat, preventing the degradation of the plastic material However, TiO2 has the ability to absorb UV radiation and convert it into heat, preventing the degradation of the plastic materialtio2 used in plastic manufacturers. This property extends the lifespan of plastic products and reduces the need for frequent replacements, making it an eco-friendly option for manufacturers.

② Plastics: At present, it is the second largest user of titanium dioxide pigments, accounting for about 20% of the total demand for titanium dioxide. The amount of titanium dioxide used in plastic products will vary with the use requirements, generally between 0.5% and 5%. According to data from the National Bureau of Statistics, the production of plastic products in China increased from 57.81 million tons in 2012 to 81.84 million tons in 2019, with a compound annual growth rate of 5.1%. The amount of titanium dioxide increases accordingly.

The production of lithopone is associated with several environmental concerns, including air and water pollution. Zinc sulfide ore mining can lead to soil erosion and habitat destruction, while sulfuric acid leaching and calcination processes can release pollutants into the air and water. To address these issues, many Chinese lithopone factories have implemented environmental protection measures such as wastewater treatment and emission reduction technologies.
