Description

Low Free PPDI/PCL Polyester Prepolymer — LFEP394

LFEP394 is a PPDI-PCL-based prepolymer featuring a very low free PPDI content, which helps improve processing safety. It offers low viscosity for easier handling and enhanced storage stability, allowing the prepolymer to remain stable without significant property changes even after extended storage. The resulting elastomer exhibits good load-bearing capacity, excellent dynamic properties, and outstanding abrasion resistance.

Key Features

  • Very Low Free PPDI Content — Enhanced processing safety with reduced exposure risk
  • Outstanding Abrasion Resistance — Superior wear performance for demanding applications
  • Excellent Dynamic Properties — Ideal for high-frequency cyclic loading environments
  • Low Viscosity — Easy handling at 800 cps (90°C) for smooth processing
  • High Load-Bearing Capacity — Excellent mechanical strength and durability
