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. The Titanium Dioxide used at Sidh Masterbatches is COATED RUTILE only- which ensures high opacity, coloring strength, dispersibility and visually appealing whiteness in the final product.
Certain grades of White Masterbatches contain mineral fillers such as calcium carbonate that provide cost reduction as well as technical benefits in many applications – especially in injection & blow moulding.
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.
