The white masterbatch is a concentration of titanium dioxide (TIO2)and resin carrier.They have perfect dispersion and optimized flow properties, so as to minimize energy consumption and improve production efficiency. The TIO2 used is rutile or anatase type,which has the characteristics of strongcoverage,high coloring strength,good dispersion,and high stability. Adding titanium dioxide in plastic,can improve the heat resistance,light resistance,weather resistance of plastic products, so that improvethe physical and chemical properties of plastic products, enhance the mechanical strength of products,extend the service life.
