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 1 395°F
Zone 2 405°F
Zone 3 420°F
Nozzle 410°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.
