CF-200i Friction Tester

The CF-200i Inclined Plane Co-efficient of Friction Tester determines the static friction properties of plastic films, foils, laminates, papers and boards. The equipment performs tests to recognised International Test Standards including ASTM D4918, G219, TAPPI T815, T503, T548 and NFQ 03083. Slide angle friction is a measurement of a sheet like substrate such as paper, plastic film, thin board, corrugated board etc. which determines the angle of inclination at which one substrate affixed to a sled will begin to slide/slip against another substrate of a similar material affixed to a bed. During a test an inclined plane bed is tilted at a rate of 1.5°+/- 0.5° per second by and electric motor until the test sled begins to slide. The initial movement of the sled is the slide angle or coefficient of STATIC friction of the material. When the test sled begins to slide a photo-optical sensor automatically stops the inclined plane bed. At that position the angle is measured and recorded, and the tangent of that angle is displayed. This represents the Coefficient of STATIC friction. A variety of factors can affect the slide angle measurement including abrasion, coatings, varnishes, printing, temperature and humidity.
