Highly efficient epoxy-functional chain extender for reactive modification of polyesters and polyacrylates.
Enables significant molecular weight build-up without gelation, even at low addition levels (typically 0.1–0.5 wt%).
Improves melt strength, melt viscosity, and thermo-mechanical stability in extrusion and compounding processes.
Compatible with a broad range of thermoplastic polymers including recycled PET, PLA, and PBT.
Supports circular economy goals by enhancing performance of post-consumer recycled (PCR) resins.
Enhancement of recycled PET (rPET) for food-contact packaging films and bottles.
Viscosity stabilization in biopolymer processing, especially polylactic acid (PLA) for thermoforming and blow molding.
Molecular weight repair in engineering thermoplastics during reprocessing or multi-pass extrusion.
Performance upgrading of polyacrylate-based adhesives and coatings requiring improved cohesive strength.
Chain extension in polyester-based thermoplastic elastomers (TPEE) to boost tensile properties and elasticity.
