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.

POSTPROCESSING
NOTICE TO USERS: Values shown are based on testing of laboratory test specimens and represent
data that fall within the standard range of properties for natural material.
These values alone do not represent a sufficient basis for any part design and are not intended for use
in establishing maximum, minimum, or ranges of values for specification purposes.
Colorants or other additives may cause significant variations in data values.

Properties of molded parts can be influenced by a wide variety of factors including, but not limited to,
material selection, additives, part design, processing conditions and environmental exposure. Any
determination of the suitability of a particular material and part design for any use contemplated by the
users and the manner of such use is the sole responsibility of the users, who must assure themselves
that the material as subsequently processed meets the needs of their particular product or use.
