Processing Recommendations

The material needs to be dried for 3 hours at 80°-90°C prior to processing, preferably using a dehumidifying drier feeded with air with a dew point lower than -30°C.

Indicative suggested molding temperature profile

Zone Temperature
Zone 1 170°C
Zone 2 175°C
Zone 3 180°C
Nozzle 175°C

Being affected by type of machine used, processing conditions and downstream equipment, the temperature profiles as given above has to be considered as just indicative. The grades suitable for extrusion are identified with the EG or AE end code and therefore they have to be ordered with such code when used in this application.
