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.
