What effect does low temperature have on urethane belting?

Urethane becomes more brittle as temperature decreases. Belts that are allowed to sit overnight in low temperature environments can take a set that is difficult to overcome at start up. This can cause even Super Strong welds to shear apart. Although urethane manufacturers often claim that regular urethane will work down to -10°F, we do not recommend using Cyclothane-A below 30°F (0°C). Our low temperature Cyclothane-E will work down to -10°F (-23°C), but for temperatures below zero F (-18°C) we recommend Hytrel ®. It will work down to -40°F (-40°C) and is especially well suited for ice cream plants. Since Hytrel is not as resilient as urethane, it should not be stretched beyond 7%. Care must be taken not to overstretch it during installation.
