As the chemical industry has developed, adhesives using synthetic polymers as raw materials have been commercialized. These adhesives are often used in a variety of industrial fields, including electronics and electrical machinery. This article introduces an example of a 90° peeling test for adhesives used in adhesive tapes.
The sample was an ordinary adhesive tape cut to a width of 24 mm and a length of 300 mm; it was set on a SUS304 stainless steel plate. An adhesive tape peeling test attachment, which is capable of peeling off tape at an angle of 90° from the plate on which the sample was set, was used as the test jig.

The test was implemented at a loading speed of 300 mm/min. After measurement started, measurement values for the initial length of 25 mm were discarded. Afterwards, the adhesive force measurement values for a length of 50 mm peeled off the plate were averaged. This average value was taken as the peeling adhesive force.
