Coefficient of Friction on Polyurethane Rollers – Polydrive

The coefficient of friction, or COF, is one of the first properties considered when determining the type of polyurethane roller needed for a particular application. Polyurethane is an extremely versatile material that can be manufactured into many different shapes, sizes, and colors, as well as be developed to varying magnitudes of hardness and degree of friction.
