PROCUCTION OF THERMOPLASTIC POLYURETHANE

摘要

PURPOSE:To produce the thermoplastic polyurethane by reactive injection molding using a high-pressure injector. CONSTITUTION:The constitution components of the thermoplastic polyurethane mainly comprises an isocyanate-terminal prepolymer obtained from an organic diisocyanate and poly(oxyalkylene)-diol and a hydroxy-terminal prepolymer obtained from poly(oxy)-alkylene diol and an organic diisocyanate.
