IOTEK
4200 is a zinc ionomer, which offers :
- good sealability, high hot tack and seal
through contamination
- good adhesion on paper, aluminium,
poly-amide and polyethylene.
- excellent draw down/neck-in balance in
extrusion coating.
- film of high impact strength and puncture
resistance
- low odor
It is primarily used for extrusion coating and film coextrusion
applications.
Processing conditions:
Extrusion coating : 275-300°C.
Blown film : 180-220°C. |
Blown
film : 180-230°C.
Higher processing temperatures favor the optical properties.
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 4200 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. |
