Of all the demands placed on conveyor belts, heat is usually the most unforgiving and damaging. High-temperature environments accelerate the aging process, which causes the rubber to harden and crack.

Our heat resistant cover compounds are superb for prolonged exposure to hot payloads and abrasives. While others note their maximum heat that is only supported for a short term load (around a minute or two), we are proud to report our prolonged heat threshold, since that is what really matters for your operation: not a minute of heat resistance, but for the entire operational period. Please note that our heat resistant cover compounds below also reach as high as 750 degrees as others report for short term loads.
