Maleic anhydride grafted polypropylene.

Category: Tag:


Maleic anhydride grafted polypropylenened recommended for sheet calendring and blow molding coextrusion. Develop reliable bond between polypropylene, propylene copolymers and many kinds of different materials among which polyamides and EVOH. 



OREVAC® 18729 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 : 210-220°C
Zone 2 : 220-230°C
Zone 3 : 230°C
Zone 4 : 230°C

Fittings-Channels : 240°C
Die : 240°C

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