What effect does high temperature have on urethane belting?
Urethane is a thermoplastic, so its physical properties decrease as temperature rises. For example, at 120oF (49oC.) its life span as measured by resiliency declines to about 70% of what it is at room temperature; at 150oF (66oC) its resiliency drops to about 10%. If you need elastic, high temperature belts try our Jacketed Spring Belts (patent pending). They will retain resiliency as high as 450oF (232oC.).
