Tioxide TR28 is the latest development in Huntsman Tioxides innovative

approach to supplying products for the masterbatch industry. Tioxide TR28

has been specially designed to meet the most demanding requirements of the

masterbatch producers. Developed through technical and market expertise, thoroughly evaluated

both on laboratory and industrial scale, Tioxide TR28 offers an even higher performance than

Tioxide TR27. It sets new performance standards in the industry. Indeed, the new technology

developed to give Tioxide TR28 its outstanding performance has been protected by patent.

Superior in tougherconditions

Tioxide TR28Standard masterbatch grade

The general trend in the plastics film industry is towards faster throughput and

higher extrusion temperatures and this has been carefully considered in the development

of Tioxide TR28.

These tougher conditions can have implications

for the TiO2 pigment for instance by causing

release of volatiles from the surface of the TiO2.

Therefore, Tioxide TR28 has been designed

to minimise the TiO2 pigments contribution to

phenomena such as die build-up and lacing.

The pictures below clearly show that Tioxide TR28 gives excellent performance in film extrusion

in terms of resistance to lacing and die build-up. This outstanding level of performance has been

well proven in the market with Tioxide TR27.

The most popular types of equipment used to prepare white masterbatches are internal mixers

and twin screws. The ease of dispersion of Tioxide TR28 is so good that you can push both

types to their working limits without reaching the performance limits of Tioxide TR28.

With Tioxide TR28, we have produced 75%

TiO2 masterbatches using an internal mixer in

the absence of any lubricant, such as stearate for

example.

We have also been able to increase the fill factor

from 75% (standard condition for standard

plastics grades) to 90% (see Figure 1), without

impairing the outstanding dispersion level of the masterbatch. In practical terms, we have

increased the output rate by about 15% on a weight basis.

We have also produced 75% TiO2 white masterbatches containing no

lubricant using a co-rotating twin screw. We have increased the

production throughput by up to 30% by weight, as illustrated by

Figure 2, whilst maintaining an extremely good level of dispersion. This

increase in throughput

was accompanied by a

reduction in power consumption.

In both cases Tioxide TR28 will allow

you to produce masterbatches, with

exceptional dispersibility levels, much

faster.

Melt flow retention

The incorporation of a TiO2 pigment into a

polymer induces a reduction in the melt flow

of the resin used. Tioxide TR28 minimises this

reduction and contributes to the development

of much more efficient processing conditions

(Figure 3).

Colour in polymers

Tioxide TR28 has been developed to give

polymers the highest brightness and a blue

tone which means the best whiteness as

illustrated in Figure 4.

When used in combination with most

coloured pigments, Tioxide TR28 has been

designed to give depth of shades and

undertones, similar to those obtained with

Tioxide TR27 or Tioxide R-FC5, thus

avoiding most reformulation processes (as

illustrated in Figure 5).
