Maleic anhydride grafted linear low-density polyethylene tie resin concentrate for barrier multilayer films. Can also be used as a coupling agent or a recycling agent.

Develop a reliable bonding strength in coextrusion processes between polyethylene or ethylene copolymers and different materials among which polyamides and EVOH.

Containing a high amount of grafted reactive functionalities in order to be used as a concentrate.  Can be used pure or blended with other polyolefins.


It can be processed within different coextrusion technologies including cast film, blown film, sheet calendaring, blow molding or tube. 
OREVAC® OE825 is to be processed like a standard polyethylene resin. Typical extrusion temperature settings could be:
Zone 1 : 160-180°C
Zone 2 : 180-200°C
Zone 3 : 200-220°C
Zone 4 : 210-230°C
Exit : 220-230°C
Fittings-Channels : 220-230°C
Die : 220-240°C

Final profile and settings will depend on the line and the multi-layer structure being run.

Storage, Handling & Safety

OREVAC® OE825 should be stored in dry conditions protected from UV-light. Improper storage conditions may cause degradation and have consequences on physical properties of the product.
