Preprocessing
To avoid hydrolytic degradation during processing, CELANEX resins have to be dried to a moisture level equal to or less than 0,02%. The drying should be done in a dry-air dryer (dew point <-30掳C) with a temperature of 120 to 140 掳C and a drying time of 2 to 4 hours. In case of longer residence times in the dry-air dryer, the temperature should be reduced to 100掳C.
The time between drying and processing should be kept as short as possible. The processing machine feed hopper should be closed during the processing operation.
Processing
Melt Temperature 265-275 掳C
Mold Temperature *) 90-100 掳C
Maximum Barrel Residence Time **) 5-10 min
Injection Speed fast
Peripheral screw speed max.0,3 m/sec
Back Pressure 10-30 bar
Injection Pressure 600-1000 bar
Holding Pressure 400-800 bar
Nozzle Design open design preferred
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.
Celanese 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 掳C 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 Notes
Pre-Drying
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掳 C. The time between drying and processing should be as short as possible.
Storage
For subsequent storage of the material in the dryer until processed (<= 60 h) it is necessary to lower the temperature to 100掳 C.
