The DuPontTM Ti-Pure R-104 titanium dioxide 

 Product Description 

 DuPont Ti-Pure R-104 is the chloride legal system to take the rutile titanium dioxide pigment. Designed to provide excellent melt fluidity for high pigment content of thermoplastic masterbatch. R-104 both high color strength and blue phase. in the high-temperature extrusion coating and lamination applications, R-104 has excellent resistance to rhegmatogenous R104 is a fine dry white powder, has the following basic properties:

 Ti-Pure R-104 is primarily designed for plastic, is especially suitable for the need of high concentrations of thermoplastic masterbatch, and the impact of the minimum system requirements on the melt flow. 

 The following properties DuPont Ti-Pure R-104 color preparation is extremely valuable. 

 Ti-Pure R-104 has the following advantages: 

 - High tinting strength and maximum blue phase 

 - Masterbatch excellent workability 

 - High resistance to rhegmatogenous 

 - Hydrophobic 

 - Highlight the dispersion of 

 - Minimal impact on the polymer melt flow 

 Ti-Pure R-104 has a special surface treatment, which makes the R-104 masterbatch manufacturers in a relatively low melt index resins for high pigment content, and still is a financial processing of materials. 

 R-104 and R-101 melt index are shown in Table three: 

 Although the melt index is a better means for the determination of relative performance, but this method can not reflect the actual processing conditions. Capillary melt flow measurements to fill such a vacancy, viscosity can be measured within the normal range of processing equipment. Figure 3 illustrates the R-104 allows 70% concentration the viscosity of the LDPE masterbatch significantly reduced. 

 Ti-Pure R-104 can be easily and thermoplastic surface wetting, and in the preparation of thermoplastic masterbatch with some mixing equipment, can greatly increase the additive-type rate of a typical mixer power curve shown in Figure 4, the figure compares the performance of R-104 and R-101 in two models of titanium dioxide. obviously shorten the processing cycle of 25% is very easy to achieve.
