Flexible, General Purpose PVC Applications

Ti-Pure® R-103
Selecting the optimal DuPont TiO2 product for flexible vinyl applications depends on the intended use of the product and the type of heat stabilizers used in the PVC compound to protect the resin during processing. For general purpose flexible applications, TiO2 product selection is based largely on optical performance and pigment handling. Ti-Pure® R-103 is the preferred product with the following key characteristics:

Ti-Pure® R-103

  • High tint strength to efficiently provide opacity
  • Blue pigment undertone for a clean white appearance

If alternative tint properties are required, Ti-Pure® R-101 is preferred for an application requiring a more neutral undertone.

Flexible, Outdoor, White and Colored PVC Applications

Ti-Pure® R-960 and R-105
Selecting the optimal DuPont TiO2 product for flexible vinyl applications depends on the intended use of the product and the type of heat stabilizers used in the PVC compound to protect the resin during processing. R-960 and R-105 are, respectively, the preferred products for exterior tinted and non-chalking white products, regardless of the heat stabilizer system used. For both products, the dense silica surface treatment minimizes chalking which is perceived as color fade in tinted products and results in loss of gloss for white applications.

 

 

Flexible, Lead Stabilized PVC Applications

Ti-Pure® R-105 and R-103
Selecting the optimal DuPont TiO2 product for flexible vinyl applications depends on the intended use of the product and the type of heat stabilizers used in the PVC compound to protect the resin during processing. Some organic lead stabilized PVC compounds pigmented with untreated TiO2 products may experience lead graying on outdoor exposure. Ti-Pure® R-105 is recommended since it combines excellent lead graying resistance with exterior durability. Ti-Pure® R-103 may also be used in flexible applications using a lead stabilized compound. While it will not catalyze lead graying, Ti-Pure® R-103 will surface chalk at a rate similar to other general purpose TiO2 products.
