Abstract:

This paper mainly describes the properties of mechanical properties, heat resistance, and dynamic mechanical properties of polyurethane elastomer based on MDI and diamine chain extenders. Compared with the polyurethane extended by diol, diamine extended MDI level polyurethane elastomer shows higher hardness, tensile strength, 300% modulus, tear strength and better heat resistance. But the soft segment relaxation shifts to higher temperature.
