R-101 Titanium Dioxide

Product Information
Product Description

Figure 1. Optical Properties

Ti-Pure R-101 is a rutile titanium dioxide pigment
manufactured by the chloride process. It is excellent
for high-temperature plastics applications requiring
outstanding dispersibility and lowest possible volatility.
The grade is a fine, dry, white powder with the following
general properties.

Suggestions for Use
Ti-Pure™ R-101 is designed primarily for plastic
applications. Ti-Pure™ R-101 provides high opacity with aneutral undertone (Figure 1).
The low level of surface treatment on Ti-Pure™ R-101
gives it excellent dry blend dispersion. Figure 2
demonstrates relative opacity strength of pigments for
simple tumble blending versus high shear dispersion.

TiO2A major advantage of Ti-Pure™ R-101 is its low levelof crystalline and surface adsorbed water. Thischaracteristic gives superior performance in hightemperature polyolefin extrusion coating operations
sensitive to lacing. The very low volatility of Ti-Pure™
R-101 is reflected in Figures 3 and 4.
