PREPROCESSING
To avoid hydrolytic degradation during processing, CELANEX resins have
to be dried to a moisture level equal to or less than 0.02%. Drying
should be done in a dehumidifying hopper dryer capable of dewpoints
<-30°F (-34°C) at 250°F (121°C) for 4 hours.

PROCESSING
Rear Temperature 450-470(230-240) deg F (deg C)
Center Temperature 460-480(235-250) deg F (deg C)
Front Temperature 470-500(240-260) deg F (deg C)
Nozzle Temper ature 480-500(250-260) deg F (deg C)
Melt Temperature 460-500(235-260) deg F (deg C)
Mold Temperature 150-200(65-93) deg F (deg C)
Back Pressure 0-50 psi
Screw Speed Medium
Injection Speed Fast

Injection speed, injection pressure and holding pressure have to be
optimized to the individual article geometry. To avoid material
degradation during processing low back pressure and minimum screw speed
have to be used. Ov erheating of the material has to be avoided, in
particular for flame retardant grades. Up to 25% clean and dry regrind
may be used.
