Altre informazioni
Stampaggio ad Iniezione
General drying is not necessary due to low moisture absorption of
the resin.

In case of bad storage conditions (water contact or condensed water)
the use of a recirculating air dryer (100 to 120 °C / max. 40 mm
layer / 3 to 6 hours) is recommended.

Max. Water content 0,2 %
Standard injection moulding machines with three phase (15 to 25 D)
plasticating screws will fit.

Conditioning e.g. moisturizing is not necessary.
