摘要

The present invention provides a manufacturing method of a template PPDI-based polyurethane nanoclay elastomer, and the template PPDI-based polyurethane nanoclay elastomer manufactured by the method. The template PPDI-based polyurethane nanoclay elastomer contains 0.3 to 0.4 wt% of nanoclay, and has a hardness of 95 or more, tensile stress at 100% elongation of 12 MPa or more, and a Vicat softening point of 190°C or higher.
