ABSTRACT:
A polyurethane elastomer exhibiting superior flex fatigue properties is obtained by reacting a mixture of isocyanate-terminated polyether prepolymers with at least one alkylthioaromatic amine curing agent. Optionally, the elastomer can be postcured for further improvement of its properties. The polyurethane elastomer can be utilized for the fabrication of a non-pneumatic tire.
