How do you tell when you need 180 degrees and a 90-degree peel test?

The peel test is an essential part of the adhesive industry. How much adhesion is required between the two surfaces, and how much force should be applied to peel-off? All of these judgements are done through analyses and detailed testing using Peel Strength Tester. These testing methods are very important in assessing the quality of tapes, adhesion products, peel-off strips etc. The most raised question and commonly discussed issue remains the degree of peel test. We must be aware that there are two degrees of the adhesion test, 180 degrees and 90 degrees. But which one is appropriate for what material? Knowing the answer to this is crucial.

How to choose the degree of the Peel Test?
Making this decision is not tough, you just need to know the right criteria. Choosing between a 180-degree and 90-degree peel adhesion tester depends on the application of the product to be tested, and the physical and chemical properties of the material. Let us know more about it in detail:

180-degree peel test is used for:

This test is used for materials where peel strength is perpendicular to the surface of the product. Some examples are materials in which one layer is removed parallel to the other layer like tapes, labels, and protective films on mobile screens or packaging and wrapping sheets.

90-degree peel test is used for:
This test is used for materials where the peeling strength is parallel to the surface of the product and one layer that is peeled is at a 90-degree angle to the other layer. Some examples are adhesive products used in building and construction, and adhesive product self-analysis on different products.

Other than these sometimes if the industry requires and the application has set standards, the manufacturer can use both 90 and 180-degree Adhesion Strength Tester.
