types of tio2

The trend in the production of NPs is likely to lead to increasing amounts of nano-powders in the air, water and soil, which will consequently affect living organisms. Labielle et al. demonstrated that 25 % of Al(OH)3-coated TiO2 particles from sunscreens are dispersed as a stable colloid and become available to microorganisms and filter-feeders, while the remaining 75 % are probably incorporated into geogenic sediments, where they could become available to benthic fauna. Solar UV iradiation may penetrate as far as 20 m in the water column  and therefore photo-activate the dispersed particles, which may have an adverse effect on various aquatic organisms.

Titanium dioxide's significance in rubber production stems from its exceptional opacity and whiteness, which significantly improves the visual appeal of products like tires, rubber sheets, and various industrial rubber goods. Its ability to scatter light effectively makes it a preferred choice for creating bright, clean white shades in rubber products. Moreover, TiO2 also imparts heat resistance, enhances tensile strength, and improves the overall mechanical properties of the rubber, making it more durable and long-lasting.
