DuPont Ti-Pure®  is a rutile titanium dioxide pigment manufactured by the chloride process. They are excellent for high temperature plastics applications requiring outstanding dispersibility and lowest possible volatility. These grades are fine, dry, white powders with the following general properties:

CIE L* is the minimum value. Organic treatment is reported as % carbon. All other values are typical. Resistance is reported as the minimum value in kilo-ohms-cms. Test methods used to determine the values reported are available from your Ti-Pure sales or technical service representative.

 

Ti-Pure® R-100 and R-101 are designed primarily for plastic applications. Chemical composition and product performance of these two grades are essentially identical except for their relative undertone tint effects.  

Ti-Pure® R-103  is an excellent general purpose grade for all resin systems, is excellent in polyolefin or engineering resin applications requiring high opacity strength, very blue tint, excellent dispersion and discoloration resistance. R-103's surface treatment allows its use in lead stabilized PVC systems, while still providing controlled chalking in exterior PVC applications.  
  
Ti-Pure® R-104 is  specifically designed to give outstanding melt flow with highly loaded thermoplastic masterbatches. R-104 combines high tinting strength and blue undertone. R-104 offers excellent lacing resistance in high temperature extrusion coating and cast film applications.  

Ti-Pure® R-900, R-902, and R-960 are also occasionally used.  

First Aid. Respirable dusts of TiO2 should be controlled in air to an exposure limit of 5 mg/m3, 8-hour time-weighted average.  
  

DuPont Ti-Pure®  is available in 50-lb (25-kg) polyethylene bags and semibulk containers (approximately 1/2 and 1 metric ton).  

Ti-Pure®  plastics grades are  listed with NSF International for use in plastic pipe products.  
  

The shelf life of DuPont Ti-Pure® TiO2 is indefinite as long as the material is kept from direct contact with moisture.  

We have specific Titanium dioxide Pigment Ti-Pure® grades from DuPont, S.A. de C.V., to be used in various applications in the industry.
