LOTEK

LOTEK 8000 (Ethylene Acrylic Acid Sodium IONOMER)

Key features

Recommended processing conditions and resin handling

IOTEK 8000 is a low melt-index zinc ionomer, which offers :

- - an optimal combination of stiffness, proc-essability and   flex-life properties
- outstanding clarity and gloss

It is typically used for sheet production and for injection moulding or profile extrusion of stiff high clarity parts.

It's excellent melt strength and toughnessmake the grade also useful for thermoforming and deep draw applications.
Melt temperature : 200 - 230 °C

Processing conditions :
IOTEK 8000 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 8000 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 .
