The present invention relates to a polyurethane microcellular elastomer, a non-pneumatic tire and a preparation process and use thereof. The polyurethane microcellular elastomer of the present invention is obtained by reaction of a reaction system comprising components such as isocyanate, ethylene diamine-started polyoxypropylene ether tetraol, a catalyst and a foaming agent. The non-pneumatic tire of the present invention has very strong fatigue resistance and can be used for non-motor vehicles running at high speed. |
