NEXAMITE® M992000: linear IV enhancer for PET filament, fiber and strapping

Turn IV increase into mechanical performance

NEXAMITE® M992000 is a linear IV enhancer designed for continuous filament, textile yarn, technical fiber and PET strapping applications. In these applications it is not only IV increase that matters, but also preserving tenacity, elongation and drawing behaviour.

The reactive masterbatch approach supports linear chain extension in the PET/rPET melt. Nexam Chemical states that the product is compatible with existing PET fiber lines and helps improve spinning stability, tenacity and drawing performance.

Key benefits

  • Helps preserve or improve mechanical properties while increasing IV.
  • Supports tenacity, elongation and drawing performance.
  • Helps enable the use of fiber-to-fiber recycled feedstock.
  • Helps improve spinning stability and reduce stoppages caused by filament breaks.
  • Designed for use on existing PET fiber production lines.
  • Can form part of a combination solution in PET/rPET/PBT foam recipes as chain extender, acid scavenger and stabilizer.

Typical applications

  • Continuous filament and textile yarn
  • PET strapping tape
  • Technical fibers
  • Fiber-to-fiber recycling
  • Combination use in PET/rPET/PBT foam recipes

Technical assessment note

Do not evaluate filament or strapping performance on IV alone. Starting IV, feedstock source, drying, spinning/drawing conditions and target tenacity–elongation values must be considered together. In foam applications the combination role of M992000 requires separate recipe validation.

Frequently asked questions

What is the difference between M992000 and M021200?
Nexam recommends M992000 for linear IV increase together with mechanical performance in continuous filament and PET strapping, and M021200 for staple/carpet fibers and sheet/thermoforming.
Can it be used in fiber-to-fiber recycling?
Nexam Chemical states that M992000 supports fiber-to-fiber recycled feedstock; line and performance validation is required.
Can it be applied on an existing line?
The product is described as compatible with existing PET fiber production lines; feedstock and trial settings must be defined through technical work.
Is it a standalone solution in PET foam?
Nexam describes a combination role with M02 solutions in foam recipes. The right combination requires technical assessment.

The technical statements on this page are based on the manufacturer’s current public product information. Dosage, temperature and performance targets are defined per line through technical trial.
