IOTEK
7020 is a low melt-index zinc ionomer, intended for molding applications.
It is typically used for injection molding
of items that need to keep
good low temperature mechanical properties.
Processing conditions:
IOTEK 7020 can be processed on equipment
normally used for LDPE.
Melt temperature : 200 - 230 °C |
Warning:
To minimize corrosion risk, all exposed metal surfaces in the extruder
and die should be made from corrosion resistant metals or nickel/chrome
plated.
Iotek 7020 should be fed into the extruder after LDPE of a similar or
higher melt index. Machines should always be completely purged with LDPE
or a suitable cleaning compound before shutdown.
Cation containing polymers pick up moisture from the atmosphere if
exposed for prolonged periods. It is therefore recommended to
re-seal tightly the package after each production run molding. |
