Slip Tester for Plastic Films

Model HV-EXP4392
Slip Tester for Plastic Films - The force needed to cause slipping between two surfaces of any plastic film depends on its co-efficient of friction. & The co­efficient of friction is the ratio of the frictional force and normal pressure acting on two surfaces in contact with each other. Thus it is an inverse measure of the relative ease with which a material will slide over a similar or different material. & The& Slip Tester for plastic films is designed to determine both static and dynamic co-efficients of friction between two flat surfaces of flexible plastic films. It consists of a rigid, smooth, and horizontal platform for mounting the test specimen on and an arrangement to measure frictional force between the test specimen mounted on it and a movable sled. & The horizontal platform is provided with a channel around its periphery for providing vacuum clamping to the film under test. A steel sled having its bottom face lined with a 3 mm thick layer of micro-cellular foam sheet is kept on top of the test specimen mounted over the platform. The sled is moved at the specified speed with the help of a screw mechanism driven by an electric motor. It is also connected to a load cell for measurement of frictional force acting on it. A peak force display arrangement enables the maximum force exerted during the slipping operation to be recorded and displayed when desired. Arrangement to automatically stop the movement of the sled at the extreme ends of travel of the load cell is also provided. &civil lab equipments manufacturers.
