Coefficient of Friction Tester is professionally applicable to the determination of static and kinetic coefficients of friction of plastic films, sheets, rubber, paper and paper board, PP woven bags, fabrics, metal-plastic composite belts for communication cables, convey belts, wood, coatings, brake pads, windshield wipers, shoe materials and tires. By testing the frictional properties of materials, the technical indexes could be controlled to meet requirements for production.
