Supplied in hermetically sealed bags, Leona pellets
do not require predrying if used immediately after unsealing.
If not used soon after unsealing, however, the pellets will
absorb considerable moisture from the air. To avoid silver streaking
and other defects caused by moisture absorption, unsealed Leona
pellets must be either stored in airtight metal containers or
predried before molding. |
Storing
To prevent moisture absorption, do not break the bag seal
until just before use. Avoid bag breakage and keep product
away from water. Do not return any spilled pellets to the
bag.
Molding
Always process Leona under the recommended temperature range.
Lower temperatures may lead to local degradation in properties
due to nonuniform plasticization, while higher temperatures
tend to cause silver streaking, other appearance problems,
and resin decomposition. As the optimum temperature range
varies among grades, read the guideline for each grade (available
from Asahi Kasei Chemicals). Ensure adequate local or general ventilation
throughout molding operation. Detention of Leona in a non-operating,
heated cylinder may cause resin decomposition. Before any
extended suspension of molding operation, purge and charge
the cylinder with non-colored polyethylene or a purging material
designed for polyamide resins. Promptly remove and discard
any spilled pellets from the work area to prevent slips and
falls.
NOTE:
The information provided here is accurate to the best of our
knowledge, based on all information and data available at this
time, and is subject to change without notice. It is provided
with no guarantee or assumption of liability whatsoever. It
applies only to the normal handling and use of Leona as a molding
material. Any other use or application would necessitate additional,
special safety precautions, and is not recommended.
