NEXAMITE® M022400: IV booster for rPET recycling lines
Rebuild intrinsic viscosity during reactive extrusion — the priority grade for the Turkish market
NEXAMITE® M022400 is an IV-boosting PET masterbatch for recycled PET lines. It raises the intrinsic viscosity lost during mechanical recycling through chain extension inside the extrusion process itself, so higher melt strength and mechanical performance can be reached without a separate solid-state polymerisation (SSP) step.
The grade is held in stock in Istanbul and is the priority product for the Turkish market. Final addition level and performance must be validated against the feedstock, starting IV, line configuration and end-use specification.

What it does
Intrinsic viscosity (IV) falls during mechanical recycling as hydrolytic and thermal degradation shortens the polymer chains. M022400 rebuilds molecular weight by chain extension during extrusion, restoring melt strength and mechanical performance — so recycled PET can be used in applications that would otherwise require virgin resin or an SSP step.
Key benefits
- Can remove the SSP process — saving energy and process time.
- Runs on existing extrusion lines; no additional capital investment required.
- Supports higher recycled content, helping meet EU PPWR targets.
- REACH and FDA compliant; documentation on request.
Typical applications
- rPET recycling plants
- PET sheet and film production
- PET strapping / band production
Technical assessment note
Treat the dosage and temperature above as a starting window, not a specification. Define the working dose together with feedstock type, starting IV, moisture management, line configuration and final performance targets, and confirm it on your own line. Keep the current declaration of compliance and conditions of use on file for food-contact work.
