High Abrasion Resistant Conveyor Belting – HARK
Conveyor belting designed for the ultimate resistance to abrasion. Equivalent to DIN-W grade with less than 90 Cu.mm abrasion loss and DIN-Y with less than 80 Cu.mm abrasion loss, these conveyor belts are developed to assure you of the longest belt lifetime. The combination of polyester in warp and nylon infilling provides technical low-stretch, high impact abuse resistance. Recommended for transporting abrasive materials, such as glass, cullet, granite, trap rock, etc.

Heat Resistant Conveyor Belting – HR
Performance proven heat resistant conveyor belting recommended to protect conveyor belting from surface cracking and hardening by heat from hot service applications like hot sintered ore, hot pellet, hot clinker, hot chemical, fertilizer and hot cement, etc. Heat and abrasion resistant cover rubber has been heat treated and dipped to minimize carcass shrinkage and heat aging.

Heat resistant belts are best suited for conveying product that is over 60º (140º F). The surface temperature of heat resistant belting varies with the material type, belt speed, loading rate and size. To select the proper heat resistant belting, consider not only the material temperature to be conveyed but the surface temperature of the belt as well.
