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 1 375°F
Zone 2 385°F
Zone 3 395°F
Nozzle 385°F

Suggested extrusion temperature profile:
 

Zone Temperature
Zone 1 375°F
Zone 2 385°F
Zone 3 400°F
Zone 4 395°F
Adapter 385°F
Die 375°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.
