Processing Recommendations

Material needs to be dried prior processing at 175-195 °F for 3 hours, preferably using a dehumidifying drier fed by air exhibiting a dew point lower than -22°F.
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 1 375°F
Zone 2 380°F
Zone 3 390°F
Zone 4 385°F
Adapter 375°F
Die 365°F

 

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.
