Withstanding the heat
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.
