HIGH TEMPERATURE POLYURETHANE BELT

摘要

A high and low temperature resistant endless belt (10) is disclosed. The belt (10) includes a main belt body portion (12) prepared from elastomeric material and a tensile member (20) disposed in the body portion (12). A sheave contact portion (14) is formed integral with the main body portion (12). 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 hydroxyl 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.
