KordFlex uses a high-tensile, extremely low-stretch aramid carcass, which has the highest strength-to-weight ratio of all the conveyor belt reinforcements used. It has a 10:1 safety factor, more than twice that of synthetic fibres like polyester and nylon, and five times that of steel.
The carcass is especially useful in weight sensitive, high abrasion, high tension applications. Kordflex, when used in place of existing steel cord belting, can result in a 70 per cent carcass weight reduction.
The transition from a steel cord belt to a KordFlex belt also offers economic benefits by having greater ‘available cover’ life. This is due to the fact that the covers can be worn down much closer to the carcass without significantly compromising its impact, tear or tensile strength, providing a minimum additional two millimetres of usable cover.
