Fenner Dunlop OptimaHeat® Xtreme


Re-Designed From the Inside Out

Of all the demands placed on conveyor belts, heat is usually the most unforgiving and damaging. High-temperature environments accelerate the ageing process, which causes the rubber to harden and crack. Heat also has a seriously harmful effect on the belt carcass itself because it damages the adhesion between the cover and the carcass and between the fabric plies contained within the carcass. This literally causes the belt to fall apart. This is commonly referred to as ‘de-lamination’. As rubber becomes harder and less elastic due to the exposure to heat the tensile strength and the elongation at break can fall by as much as 80%. This effectively destroys its operational strength and flexibility. At the same time, resistance to abrasion can decrease by as much as 40% or more. As the reference guide below shows, Fenner Dunlop heat resistant belts not only withstand heat extremely well, they also provide exceptionally long wear life compared to its rivals.

OptimaHeat – New generation of Hot Belts has arrived.

The name stems from the latin word “Optima,” which refers to the greatest degree attained under specified conditions. And that is what we have done; created a carcass and cover combination single unit product that will last longer in higher heat conditions. Re-designed from the inside out, OptimaHeat Xtreme contains enhanced properties across the board, with superior adhesion strength, better abrasion resistance, more reliable vulcanized splice reliability, and the ability to resist hardening and cracking while carry hot materials up to 750F*. Optimize your belt life in higher heat applications with OptimaHeat Xtreme, a Fenner Dunlop X Series Conveyor Belt.”

*Maintaining a belt surface temperature under 400 degrees F will maximize belt life.
