Highly efficient multi-functional epoxy-based chain extender for thermoplastic polyurethanes (TPU) and polyesters.
Enables precise molecular weight control and improved melt strength during extrusion and injection molding.
Enhances mechanical properties—including tensile strength, elongation at break, and tear resistance—without compromising processability.
Compatible with a broad range of polyols and isocyanates; supports low-temperature processing windows.
Non-volatile, low-dust powder form ensures safe handling and consistent dosing in industrial compounding lines.
Reinforcement of thermoplastic polyurethane (TPU) compounds for automotive interior trim and seals.
Performance enhancement of polyester-based engineering plastics used in consumer electronics housings.
Molecular weight stabilization in recycled PET and PBT blends for sustainable packaging applications.
Chain extension in biodegradable aliphatic polyesters (e.g., PBAT, PLA) for flexible film and fiber production.
