Processing Recommendations

Before processing, material needs to be dried at 175-195°F for 3 hours, preferably using a dehumidifying drier fed by air with a dew point lower than -22F°C.
Suggested molding temperature profile:

Zone Temperature
Zone 1 355°F
Zone 2 365°F
Zone 3 375°F
Nozzle 365°F

Suggested extrusion temperature profile:

Zone Temperature
Zone 1 355°F
Zone 2 365°F
Zone 3 375°F
Zone 4 375°F
Adapter 355°F
Die 350°F

 

Being affected by the type of machine used, processing conditions and downstream equipment, the suggested temperature profiles has to be considered as just indicative.
