Description

Low Free NDI/PCL Polyester Prepolymer — LFEN393

LFEN393 is an NDI-PCL-based prepolymer featuring low viscosity and enhanced storage stability. It can be stored for over 12 months without any significant change in properties, allowing for reliable and consistent processing. The resulting elastomer exhibits excellent dynamic properties, making it particularly suitable for applications subject to high dynamic loads.

Key Features

  • Low Free NDI Content — Improved processing safety and reduced health risks
  • 12-Month Storage Stability — Maintains consistent properties throughout extended storage
  • Excellent Dynamic Performance — Ideal for high dynamic load applications
  • Low Viscosity — Easy handling and processing at 90°C
  • High Rebound — 62% Bayshore rebound for superior energy return
