Ti-Pure™ R-104 has a unique surface treatment that causes it to have minimal effect on the melt flow properties of masterbatches. This allows the masterbatch producer to achieve high loadings in relatively low melt index resins and still have a melt processible material. The effects of Ti-Pure™ R-104 and Ti-Pure™ R-101 on melt index are shown in Table.

Capillary melt flow measurements fill this gap, allowing viscosity to be measured over the normal range of processing equipment. Figure 2 shows the profound reduction in viscosity that can be achieved with Ti-Pure™ R-104 in a 70% low density polyethylene masterbatch.

Ti-Pure™ R-104 easily “wets” with the surface of the thermoplastics and can dramatically increase process rates during preparation of thermoplastic masterbatches in certain types of compounding equipment. A typical internal mixer power curve is shown in below figure, which compares Ti-Pure™ R-104 and Ti-Pure™ R-101 grades of titanium dioxide. It is apparent that cycle time reductions of up to 25% can be readily achieved.

Ti-Pure™ R-104 is designed primarily for plastic applications. The properties of Ti-Pure™ R-104 are especially valuable where high concentrations of pigment are desired in thermoplastic masterbatches and where minimal effect is desired on melt flow. This, combined with the following, makes Ti-Pure™ R-104 a valuable asset to the color formulator.
