Injection molding

To achive low emission values pre drying using a recirculating air dryer (100 to 120 °C / max. 40 mm layer / 3 to 6 hours) is recommended.

Max. Water content 0,1 %
Standard injection moulding machines with three phase (15 to 25 D)
plasticating screws will fit.

Conditioning e.g. moisturizing is not necessary.
