In all the varieties of masterbatches used in plastic applications, white masterbatch is the one which is most used. White Masterbatch provides whiteness, brightness and opacity to the final product. A variety of chemicals such as titanium dioxide, antimony oxide, zinc oxide and zinc sulphide are used to provide these properties in plastics. Some of the main reasons for use of titanium dioxide is for its special properties such as average particle size (.19 to 0.22 micron),high refractive index etc.
Our range of white masterbatches is based on superior quality titanium dioxide. The titanium dioxide, which we use is selected on the basis of its excellent properties such as undertone, color and opacifying / tinting strength. It has a unique surface treatment that offers good dispersion in plastics and has no effect on rheological properties of a polymer. In case the titanium dioxide doesn't properly disperse in plastics, it may lead to insufficient use of pigment and a loss of optical and mechanical properties. 

Our white masterbatches are unique in a way that they contain specialty additives, which makes the resin compatible with titanium pigment. It also makes the resin to flow so that it gets dispersed properly. We supply these masterbatches in different varieties, which depends on the percentage of titanium dioxide and tone required ie. egg tone, bluish tone, violet tone etc. It also depends on the end use application and processing techniques. We manufacture white masterbatches containing upto 70% titanium dioxide content in them.
