- Ti-Pure™ R-104 Titanium Dioxide Pigment is designed primarily for plastic applications.
- The properties ofTi-Pure™ R-104 Titanium Dioxide Pigment 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, makesTi-Pure™ R-104 Titanium Dioxide Pigment a valuable asset to the color formulator.
- Ti-Pure™ R-104 Titanium Dioxide Pigment 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.

Capillary melt flow measurements fill this gap, allowing viscosity to be measured over the normal range of processing equipment.
Technical Details & Test Data
- Techical Information
Figure.1 shows the profound reduction in viscosity that can be achieved with Ti-Pure™ R-104 Titanium Dioxide Pigment in a 70% low density polyethylene masterbatch. Ti-Pure™ R-104 Titanium Dioxide Pigment 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 Figure 1, which compares Ti-Pure™ R-104. It is apparent that cycle time reductions of up to 25% can be readily achieved.
