White Masterbatch

White masterbatches are the concentrates of titanium dioxide (TIO2) in a polymer carrier. They have perfect dispersion and optimized flow properties resulting to maximum hiding power and easy processing. 

TIO2 used is RUTILE COATED type, which ensures high opacity, colouring strength, dispersibility and excellent U.V. stability. Certain types contain as filler in form of a fine calcium carbonate that provides economy as well as technical benefits in many applications, especially in injection & blow mouldings.

For relatively thick films (40-200 microns), the most suitable masterbatches contain 40-60% of TIO2. For thin films, masterbatches with high content of TIO2 and having the best possible dispersion are preferable. There are certain specially designed grades with additives like anti-stat (for PP thermoformed items), slip (most suitable for LDPE), PPA to reduce die build up, melt fracture & surface defects and U.V. stabilizers.
