Polymers, Light and the Science of TiO 2

Tech Paper | Supplied by Chemours

TiO2 is a multifaceted material when used in polymer applications. It has been long established as the leading white pigment, and this is the application that people are most familiar with. However, titanium dioxide brings more to the polymer industry than just white, bright opacity. In a more basic sense, titanium dioxide is a photo-responsive material—its value is in its interaction with light. For example, this interaction can be the familiar scattering that results in opacity or it could be the absorption of UV light energy, thereby protecting the polymer from UV degradation. Applications continue to develop, all based on the interaction of the titanium dioxide particle with light.
