180° 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 180° 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 end of the tape was gripped and the tape was folded back 180° so that the back sides of the tape contact each other. Then a 25 mm length of tape was peeled from the plate. The end of the plate where the tape was peeled off was fastened to the lower jig attached to the tester, and the adhesive tape was fastened to the upper 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.
