Millennium Chemicals has developed a highly durable titanium dioxide that retains good optical properties. Tiona 696 is an encapsulated grade targeted for PVC decking, windows and fencing, as well as agricultural films.

“There is other encapsulated TiO2, but there has always been a need to trade off optical properties and durability,” explains Martin Painser of Millennium. “We use a second additive to improve the durability so we can scale back on the silica encapsulation.”

The result is that processors can use less Tiona 696 to achieve the durability of current superdurable products.

In addition, narrow particle size distribution produces higher opacity in thin films. An organic surface treatment provides better wetability for improved dispersion.
