| Introduction | PPDI is mainly used for special casting polyurethane elastomer and thermoplastic polyurethane.
A PPDI-based polyurethane elastomer, which shows excellent processability by ensuring sufficient service time by virtue of the low viscosity of a prepolymer and a low reaction rate with a chain extender, and allows preparation of an elastomer having a medium hardness, particularly a harness of about 80-90A.
