Novex - Resource Center - About the Product

In comparing the weight loss of a RMA Grade II rubber compound formulation, commonly used in rubber covered conveyor belting and conveyor belt wiper/scraper rubber, to CU-85 you can see that the CU-85 has 93% less weight loss and in effect has 13.7 times more abrasive wear resistance. The Taber Abrasion test.

Conveyor system - Wikipedia

Conveyor systems require materials suited to the displacement of heavy loads and the wear-resistance to hold-up over time without seizing due to deformation. In cases, where static control is a factor, special materials designed to either dissipate or conduct electrical charges. Example of conveyor handling materials.
