Type of adhesive peel test

Peel strength Tester is one of the suitable methods used in the industry to analyze the strength and efficiency of adhesives used to package different products. This test method is an appropriate method to ensure that an adhesive is suitable for a specific application. This testing procedure is carried out with the aid of a testing instrument known as a peel strength Tester. This instrument provides accurate analysis of the strength of adhesives used in the industry.

Three types of peel tests were performed on the adhesive to test the strength and efficiency of the adhesive used in the industry. The three peel tests include T peel test, 90 0 peel test and 180 0 peel test.

T peel test

The T-peel test is a type of tensile test that measures the force required to separate two flexible adhesives that are bonded together. In this type of test, the sample is prepared with two open ends. The ends are secured in clips. After that, the grips move away from each other. When the handles are separated, the substrates are peeled off from each other. The instrument's load cells measure the force applied to the substrate.

Types of Adhesive Peel Test with Figure 1

90°peel test

In the 90 ° Peel test, the test sample is placed on a rigid substrate with the open end of the adhesive placed in the handle. After that, separate the handles. This causes the adhesive to peel from the substrate to which it is applied. Load cells in the instrument measure the amount of load applied to the adhesive. In this test method, the applied force is perpendicular to the direction of adhesive peel.

180°peel test

This test is also performed identically to the 90 ° test. The only difference between the two is that in this test, the force is applied to the adhesive in the same direction as the adhesive peels.
