Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.

  • One of the primary benefits of using titanium dioxide in plastic manufacturing is its ability to enhance the appearance of the final product. The pigment provides excellent opacity, which means that it can effectively hide any imperfections or discolorations on the surface of the plastic material. This results in a more aesthetically pleasing product that appeals to consumers.
  • The R-996 pigment is also known for its excellent weather resistance and heat stability
  • On the other hand, Westerhoff said, there are hundreds of studies showing no adverse effects from the substance.

  • China’s TiO2 exports were booming in 2016. The continuously depreciating RMB and the increasing export scales of China’s manufacturers have strengthened this development throughout the year. As a fact, many of China’s producers exported their products with a lower price while achieving higher profit margins in the domestic market of TiO2. Tranalysis, a trade analysis provider, now reveals the top 10 Chinese TiO2 exporters of the year 2016 with the original data of China Customs.
