A high and low temperature resistant endless belt is disclosed. The belt includes a main belt body portion prepared from elastomeric material and a tensile member disposed in the body portion. A sheave contact portion is formed integral with the main body portion. The elastomeric material has high and low temperature resistant properties. The elastomeric material is formed from the reaction product of an amine or hydroxy terminated polyol, an hydroxl or amine terminated chain extender, and a polyisocyanate-containing composition adapted for rapid reaction with the extender when admixed therewith in a mold to retain flexibility and resiliency over heat age of the belt.
