[Scope of Application] The friction coefficient refers to the ratio of the frictional force between two surfaces to the vertical force acting on one of them. The friction performance of a material can be characterized by its dynamic and static friction coefficients. The friction coefficient meter is suitable for measuring the static and dynamic friction coefficients of plastic films and sheets, rubber, paper, cardboard, woven bags, fabric styles, metal composite belts for communication cables and optical cables, conveyor belts, wood, coatings, brake pads, wipers, shoe materials, tires, and other materials when sliding.
