lithopone for plastic

The advent of micronized TiO2, also known as titanium dioxide, has revolutionized various industries, from paints and coatings to food coloring and sunscreen lotions. This ultra-fine version of TiO2 boasts enhanced properties such as improved brightness, greater pigment performance, and superior UV protection due to its increased surface area. As the demand for micronized TiO2 grows, factories around the globe have adapted their methodologies to cater to this specialized market.

The composition of lithopone underscores its superiority in specific applications. Ideally, prepared lithopone consists of 30 to 32 percent sulfide of zinc, and a negligible percentage of zinc oxide (1.5%), with the remaining majority being barium sulfate. These attributes render lithopone nearly comparable to the best grades of French process zinc oxide in terms of whiteness. Furthermore, its oil absorption, which sits between lead carbonate and zinc oxide, solidifies its position as a functional and efficient white pigment.
