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.
