Wanthane® 1190

DRYING
Wanthane® materials are supplied pre-dried in moisture
guarded bags. Dry Wanthane® will rapidly absorb moisture
when exposed to atmosphere. For trouble free products,
Wanthane® 1190 must be dried before processing. It is
recommended to dry the material at 100-110 oC for 2-3 h in
a circulating air or dehumidified air dryer. The moisture
content must be lower than 0.03% before and during
processing.
PACKAGING
Wanthane® 1190 is packaged in the form of uncolored
transparent pellets in PE-lined bags of 25 Kg net weight
(1000 Kg/pallet).
STORAGE
Wanthane® should be inspected to assure containers are
not broken during transportation. Containers should be
stored in a cool and dry environment, and should be
brought to room temperature before opening in order to
prevent condensation. Once being used, containers with
residual materials should be sealed. It is necessary to
cover the feed hopper of the processing machine.
PROCESSING RECOMMENDATIONS
Based on our experience, the features of recommended
screw are the following:
1.
L/D ratio between 25 and 30.
2.
The appropriate compression ratio is from 1:2 to 1:3.
3.
The screw extruder should have three sections which
have continued constant pitch. The distance between
screw and barrel should be 0.1 to 0.2 mm. Depending
on the size and type of the screw and die, the breaker
plates used should have holes of 1.5 to 5 mm.
4.
TPU is shear sensitive, for this reason, the extruder’s
speed should be low in case of degradation during
processing.
TYPICAL PROCESSING CONDITIONS
Wanthane® 1190 can be both extruded and injection
-molded. Typical processing conditions are listed in the
