Titanium Dioxide Based White Masterbatches are useful for plastic processors. These White Masterbatches are based on titanium dioxide that has various properties such as undertone, colour and opacifying or tinting strength. These White Masterbatches are based on surface treated titanium dioxide which offers good dispersion in polymers and has no effect on rheological properties of a polymer. Titanium Dioxide Based White Masterbatches are hygienically processed to ensure safety of usage.
