K-Atex Flame Retardent
K-Atex flame retardent elevator belts are similar to NBR belting but flame retardent according to ISO 340. The plies are polyester interwoven with Nylon layers. The belt is made out of NBR (Nitrile Butadiene Rubber).
Thanks to a special addition in the rubber, this belt is also flame-retardant. The covers make it possible that the elevator bolt head will fit and countersunk perfectly. These belts are available in several breaking loads and thicknesses.
NBR (Nitrile Butadiene Rubber) covers are suitable for transporting products with a higher fat, oil content and a limited acid content. Ideal for the feedmill industry and raw materials intake such as sunflower seeds, fish meal, tapioca and mais. But also for polluted glas cullets.
Belts are cut and punched according to customers specifications.
