Highly reactive aromatic diamine-based chain extender for polyurethane and thermoplastic polyurethane (TPU) systems.
Enables excellent mechanical properties including high tensile strength, tear resistance, and abrasion resistance.
Offers improved processing stability and reduced viscosity during melt processing compared to conventional chain extenders.
Delivers superior thermal and hydrolytic stability in demanding end-use environments.
Compatible with a broad range of polyols and isocyanates, supporting flexible formulation design.
High-performance thermoplastic polyurethane (TPU) elastomers for automotive interior components.
Industrial hose and tubing requiring dynamic flexibility and long-term durability.
Footwear midsoles and outsoles demanding resilience, energy return, and fatigue resistance.
Roller coverings and industrial belts exposed to continuous mechanical stress.
3D printing filaments based on TPU for functional prototyping and end-use parts.
