  • Basic information

Characteristics

  • FORTIMO™ 1,4-H6XDI has a compact and highly symmetrical structure that forms a well-organized hard segment phase in reaction with chain extender, such as 1,4-burandiol.
  • Polyurethane based on FORTIMO™ 1,4-H6XDI achieves elasticity, heat resistance and light stability that was not able to be realized with conventional diisocyanate.
  • Thermosetting polyurethane (TSU) shows improved flexural fatigue properties with good stability of the prepolymer.
  • Thermoplastic polyurethane (TPU) shows superior resilience, compression set and shorter demold time in injection molding.
