Highly efficient epoxy-functional chain extender for polyesters, polyacrylates, and other hydroxyl- or carboxyl-terminated polymers.
Enables precise molecular weight control and improved melt strength without significant viscosity increase.
Compatible with standard processing equipment; requires no special handling or inert atmosphere.
Delivers excellent thermal and mechanical property enhancement in recycled and virgin polymer systems.
Low volatility and minimal odor — supports safer industrial handling and compliant processing environments.
Enhancement of recycled PET (rPET) for high-performance fiber, sheet, and injection molding applications.
Molecular weight stabilization in polyester-based thermoplastic elastomers (TPEs).
Viscosity and toughness improvement in waterborne acrylic and polyester dispersions.
Chain extension in biodegradable polyesters (e.g., PBA, PBS, PBAT) for film and packaging grades.
Performance upgrade of engineering thermoplastics containing reactive end groups during compounding.
