We have some 1/4 thick rubber flaps acting as valves in return piping transporting pulverized coal. They are Not in main stream flow, but subjected to continuous gravity return flow of coarse particles. several Angle iron strips are bolted to the rubber to enforce bending in one direction only.
Many of The originals reportedly have worn thru after about a year's service. I have asked for the worn parts to be sent here for evaluation.
They came from China and are of an unknown material.
We need to make or buy some replacements quickly.
My first choice (guess) would be some kind urethane material.
What material generically would offer the best abrasion resistance with good flexibility?
thanks,
Dan T
