Features & Benefits

Materials Features

Excellent Dispersibility,

High Temperature Strength,

Lacing Resistance,

Low Volatility,

Strong Opacity

Product Highlights

A major advantage of Ti-Pure™ R-101 is its low level of crystalline and surface adsorbed water. This characteristic gives superior performance in hightemperature polyolefin extrusion coating operations sensitive to lacing. The very low volatility of Ti-Pure™ R-101 is reflected in the below figures.

Suggestions for Use

• Ti-Pure™ R-101 is designed primarily for plastic applications and is listed with NSF International for use in plastic pipe products.
• Ti-Pure™ R-101 provides high opacity with a neutral undertone.

• The low level of surface treatment on Ti-Pure™ R-101 gives it excellent dry blend dispersion. The below figure demonstrates relative opacity strength of pigments for simple tumble blending versus high shear dispersion.
