What is peel adhesion?
I noticed "peel adhesion" on the data sheets of two of the tapes I am considering purchasing. What does this testing method show?
Peel adhesion is the relative adhesion to a surface. Results of this test are surface dependant and are heavily influenced by the testing angle, usually 90 degrees or 180 degrees.
Most of the time you will see "peel adhesion to stainless steel-180 degrees" on a data sheet. This means the tape was adhered to stainless steel, a substrate with polar surface energy. The tape will then be pulled off at 180 degrees. The force required to remove the tape is the peel adhesion and usually stated in onces per inch.
You need to consider the surface energy of the substrate you plan on adhering your product to when looking at peel adhesion. The results will not be the same for something more or less polar.
