Extrusion Conditions of “KURARITY TM”
Moisture Absorption of “KURARITY TM”
23 24
● KURARITY TM must be dried prior to processing when using non-vented extruder (hot air dryer, 60℃�, no less than 4 hours).
● The screen pack should consist of two 80 and 100 mesh screens to remove any impurities that may damage the die, and also to ensure sufficient back pressure.
● A water cooling bath (5~30℃) is recommended for the cooling of KURARITY TM. * Air cooling or shower may give insufficient cooling, and also generate vibrations that may cause defects in appearance.
● The edge and inner surface of the die should be well-finished to achieve high- quality appearance.
● When switching from other resins, dismantling and cleaning of the extruder screw and die components is recommended to prevent contamination. Purging with polypropylene or polyethylene is recommended to remove residual KURARITY TM in the extruder.
※ single screw extruder with the following specs is recommended; � -machines using TPU, PVC� -full-flighted screw, L/D=24-28, compression ratio=2.5 - 3.1
