Friction and Peeling

The COF-01, COF-01A and FPT-F1 devices measure the static and kinetic coefficient of friction of plastic films, sheets, paper, cardboard, fabrics, rubber and other materials. The PSPT-02 specifically measures the friction of catheters and guide wires in medical technology.

The COF-01 friction coefficient tester is the standard friction tester for every laboratory and is characterized by very high accuracy and is aligned to a total of four standards. For testing the coefficient of friction even at higher temperatures, the COF-01A model is suitable up to temperatures of 90°C.

The FPT-01 is a friction and peel-off tester that can test both static and dynamic coefficient of friction as well at elevated temperatures, as well as peel-off resistance of adhesive materials at 180° peel angle.

The BLD-01 is limited to pull-off resistance but can handle higher forces.
