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. Overheating of the material has to be avoided, in particular for flame retardant grades. Up to 25% clean and dry regrind may be used.

Processing
Pre Drying
Necessary low maximum residual moisture content: 0.02%
 
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 <-40℉ (-40℃) at 250℉ (121℃) for 4 hours.
 
For subsequent storage of the material in the dryer until processed (<= 60 h) it is necessary to lower the temperature to 100℃.
 
Drying time (h):4
Drying temperature (℃):120 - 130
