Tension roller is an important component in the cold rolling and pickling line of the steel industry, which can straighten, level and drive steel plates, it is one of the key factors determining steel plates.

Traditional mesh rollers or neoprene rollers are used to pinch steel plates, which can easily scratch the surface of the steel plate and affect product quality. The neoprene roller has poor wear and tear resistance. And polyurethane elastomer has excellent wear resistance and a large friction coefficient, so it has a large clamping force on the steel strip, no slipping phenomenon, accurate measurement and cutting dimensions, and does not scratch the surface of the steel strip. The appearance quality of the product has significantly improved, and the service life has been extended from the original 20-25 days to about one year before replacement, increasing the service life by 15-20 times.

POLYWIN provides stable urethane prepolymers for rollers, which have superior wear resistance, tensile strength, and tear resistance, as well as certain oil resistance, and can adapt to harsh environments.
