the long term. This article presents an in-depth
analysis of the purpose of TiO 2 masterbatch,
examines the multiple applications of white mas-

enhance the gloss with the help of masterbatch
technology. It will equally usher you into making
appropriate choices of the white masterbatch to
suit specific applications.
Understanding White Masterbatch and Its
Core Components

centration of titanium dioxide ( T i O 2 ), carrier
resins, and process additives, chiefly created
