90° Peeling Test for Adhesive Tapes [Standard No. ISO 29862:2007 (JIS Z 0237:2009)]

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.

Measurements and Jigs

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.

• A high-precision load cell is adopted. (The high-precision type is class 0.5; the standard-precision type is class 1.)
  Accuracy is guaranteed over a wide range, from 1/500 to 1/1 of the load cell capacity. This supports highly reliable test evaluations.
• Crosshead speed range
  Tests can be performed over a wide range from 0.001 mm/min to 1,000 mm/min.
• High-speed sampling
  High-speed sampling, as fast as 1 msec.
• TRAPEZIUMX LITE X operational software
  This is simple, highly effective software.
• Jog controller (optional)
  This allows hand-held control of the crosshead position. Fine position adjustment is possible using the jog dial.
• Optional Test Devices
  A variety of tests can be conducted by switching between an abundance of jigs in the lineup.
