Gliding test

Products used for coating rubber profiles can be tested by measuring the coefficient of friction or sliding friction (COF). The diagram shows the apparatus used for this measurement. Essentially, the method measures the coefficient of friction, the force required to drag a weight across a glass or metal plate coated with the gliding agent.

The more easily the rubber weight can be dragged, the better is the gliding performance of the product and the smaller the coefficient of friction.
