Friction factor

[dicksewerrat]

Hello, I'm a Civil Engr. and cannot find this info. Does anyone know what the friction factor is between two sheets of polyurethane as one a pulled across the other.

It depends very much on the grade of PU.

Contact the raw material manufacturer for details on their specific grade

There will be a lot of friction between two elastomers. However, as Pat said, PU is not one material, there are thousands of different types, each with a different coefficient of friction. In fact, all PVC flooring is coated with polyurethane to improve wear resistance and to tune the gloss and friction levels.
