Co-Efficient Of Friction Tester

Polyplast offers a wide range of affordable property testing equipment of uncompromising quality. During transportation and storage, friction between products or friction between products and surfaces often causes irreparable damage. Co-efficient of friction is the ratio of frictional force to gravitational force acting perpendicular to the two surfaces of contact. Measurement of frictional properties are made on a film or sheeting specimen when sliding over itself or another substance. PolyPlast co-efficient of friction testers employ a metal sled covered by the film under test, which is allowed to slide across the platform. A motor tilts the platform. When it reaches a certain angle of tilt the sled starts sliding down. The instant it starts to slide, the degree of tilt is shown on the semi-circular scale. The tangent value of that angle is the co-efficient of friction. Direct digital reading of the co-efficient of friction is also available. This test is valuable to companies dealing in plastic packaging (Standard ASTM D-1894).
