THERMOPLASTIC POLYURETHANE FROM LOW FREE MONOMER PREPOLYMER

摘要

Thermoplastic polyurethanes (TPUs) prepared using low-content free isocyanate monomer (LF) prepolymers, such as prepolymers based on p-phenylene diisocyanate (PPDI) with low free isocyanate content, have unique performance characteristics, For example, excellent tear strength, low compression set, and high temperature mechanical strength.
