HIGH TEMPERATURE POLYURETHANE BELT

摘要

A high and low temperature resistant endless belt (10) is disclosed. The bel t (10) includes a main belt body portion (I2) pre- pared from elastomeric material and a tensile member (20) disposed in the bo dy portion (12). A sheave contact portion (14) is formed integral with the main body portion (12). The elastomeric material ha s 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 termi- nated chain extender, and a polyisocyanate-containing composition adapted fo r rapid reaction with the extender when admixed therewith in a mold to retain flexibility and resiliency over heat age of th e belt.
