Resin should be dried before molding because excessive
moisture will result in nozzle drool, reduced mechanical
properties, poor surface appearance, and sprue sticking.
Extremely wet resin will result in a foamy extrudate. The
target moisture level is 0.03 to 0.06% (300 to 600 ppm)
and the maximum recommended drying temperature is
135°C (275°F).
Although Amodel resins are shipped with less than 0.15%
moisture and packaged in moisture-proof foil-lined bags
or boxes, the resin should be dried for optimum molding
results. The preferred drying condition is 4 hours at 120°C
(248°F). Alternatively, the resins can be dried for 8 hours
at 90°C (194°F). In either case, a desiccant bed dryer with
a dew point below -30°C (-22°F) should be used.
Drying Tips:
•Do not open containers until ready to process.
•Drying at temperatures higher than 125°C (257°F) may result in
the darkening of natural colored pellets.
•If a thermogravimetric moisture analyzer is used, it should be set
to 170°C (338°F)
•Amodel resin inan open container needs to be dried as shown in
the following table. The recommended drying time depends on
how long the container has been open and the estimated relativehumidity.
