Profile extrusion
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 extruders with grooved feed zone and short compression
screws (minimum 25 D) will fit.

Melt temperature 180-190 °C



Conditioning e.g. moisturizing is not necessary.

In case of very thick wall thickness profiles after-annealing it is
recommended to reduce internal stress.

Annealing temperature 130-140 °C
Annealing time 10 min/mm thickness
