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. For grades containing flame retardants, a maximum temperature of 265℃ should not be exceeded.
 
Ticona recommends only externally heated hot runner systems.
 
*) For moulded parts with especially high requirements to the surface quality or dimensional stability, a mold temperature of up to 110℃ can be advantageous.
 
**) If the cylinder temperatures are higher than the recommended maximum temperatures, the max. residence time in the barrel has to be reduced.

Processing
Pre Drying
Necessary low maximum residual moisture content: 0.02%
 
CELANEX should in principle be predried. Because of the necessary low maximum residual moisture content the use of dry air dryers is recommended. The dew point should be =< - 30° C. The time between drying and processing should be as short as possible.
 
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):2-4
Drying temperature (℃):120 - 140
