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 1 330°F
Zone 2 340°F
Zone 3 350°F
Nozzle 340°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.
