Coefficient of Friction

Testing applications of Coefficient of Friction (COF) are introduced.
[Coefficient of Friction (COF)] introduces testing to evaluate coefficient of friction of samples such as paper and packaging film. Contact us for COF testing of touch panel, floor, and coated surface, etc.

Coefficient of Friction(COF)

Coefficient of Friction Measurement for Writing Materials

This video is about measurement friction force of a pen, one factor of writing comfort, by using our variable weight reciprocating friction test jig. You can also generate vertical force like writing pressure by placing weight you prepared on the plate. The test result is easily graphed or calculated into coefficient of dynamic friction by supplied software. You can also overlay the graphs and compare test results of different types of pens.

Coefficient of Friction Measurement for Papers (Complies with the corresponding part of JIS P8147: 2010)

To determine coefficient of friction (COF) of paper, pull the weight with sample to slide it against the sample on the table, then calculate the COF by the supplied software. It complies with the corresponding part of JIS P8147: 2010. IMADA offers the dedicated testing system such as the following configuration, which is widely used in quality control and R&D.
