LFEP394 – High-Stability PPDI/PCL Prepolymer with Low Viscosity for Vibration-Damping Components

LFEP394 is a PPDI-PCL-based prepolymer featuring very low free PPDI content, which enhances processing safety. It offers low viscosity for easier handling and improved storage stability, maintaining consistent properties even after extended storage. The resulting elastomer delivers excellent load-bearing capacity, dynamic performance, and outstanding abrasion resistance.
