In grafting maleic anhydride onto polyethylene, the difference between a premium compatibilizer and an inconsistent one is process control. Twin-screw reactive extrusion gives manufacturers precise command over residence time, temperature profile, and monomer dosing.
Tight control of these variables minimizes unreacted monomer and crosslinking side reactions, which in turn stabilizes the Melt Flow Index (MFI) and the grafting rate from batch to batch.
For downstream cable extrusion lines, a stable MFI translates directly to predictable processing, smoother surface finish, and fewer line stoppages.
