LOTEK

LOTEK 7610 (Ethylene Acrylic Acid Zinc IONOMER)
Key features Recommended processing conditions and resin handling

IOTEK 7610 is a low melt-index zinc ionomer, which offers :

- high durability and resilience
- high impact strength
- good mechanical properties

It is typically used for sheet extrusion and in-jection molding applications.

Processing conditions:
IOTEK 7610 can be processed on equip-ment 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 7410 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
