Description

Maleic anhydride grafted polypropylene used as an adhesive or a tie layer in applications where mechanical and adhesive performances at high temperatures are required.

Bonds to polypropylene, EVOH, PA. 

Can be used as an adhesive in 3 layers polypropylene coatings (epoxy primer / adhesive / polypropylene) for external protection of steel pipe. 

Processing

OREVAC® 18732 is not corrosive and is readily processed with standard polyolefin equipment. Conditions typically used in extrusion of polypropylene resins are suitable. 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 : 215-230°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.
