Handling recommendations

Processing adviceStorage

We have developed TPU film and sheet materials for special• Our TPU grades should be stored in cool and dry conditions,processes including:• TPUs are hydroscopic, meaning that dry pellets can absorb• Cast-film extrusion

if possible at room temperature.

up to 1,5 wt. % of moisture relatively quickly if packaging is left
open. After use, seal any packaging promptly to protect

any remaining material.

• Keep material dry during processing by covering the feed
hopper whenever possible.

Drying• To ensure optimal processing performance, materials must
be dried before processing. Water content of the granulate

should not exceed 0,02 wt. %.

• Desiccant air dryers, circulating air dryers and vacuum• Flat-die or T-die extrusion• Blown-film extrusion• Laminating and embossing.
Our TPU grades can be extruded either by flat-die extrusion or

blown-film extrusion (annular die). Although blown film extrusion
is more suitable for the production of very thin films (<20µm),

and flat-die extrusion is more suited to sheets (>250µm), bothprocesses can be used to achieve a very broad range of film or

sheet thicknesses. With blown films, the addition of anti-blocking
agents as well as the use of a carrier (i.e. supporting foil) makes
the entire process easier.

drying ovens can be used to reduce the moisture content of
the granulates before processing.

• Drying recommendations depend on the hardness of the resin,chemical structure and drying process. For TPUs with a

Shore A above 90, a higher drying temperature is typicallyrequired. For drying conditions for specific TPU grades, pleaserefer to the respective technical datasheet.

Coloring & additives• Our TPU elastomers can be opaque or transparent, dependingon their processing route and microstructure. They can becolored using a masterbatch with typical amounts ranging from
1 to 4 wt. %, depending on the thickness of the final productand the pigment concentration in the masterbatch.

• Using an incompatible masterbatch may cause poor pigment

dispersion as well as a poor surface finish with surface defects.

• Different types of additives (UV stabilizers, anti-blocking

Flat-dieextrusion line

agents, release aids, etc.) can be added to our TPU
grades to enhance material properties.

• It is important to ensure that color or additive masterbatches

do not contain any moisture. For that reason, masterbatches
used during the processing of our TPU grades should be
pre-dried appropriately.
