There are many different methods to test the adhesion of a tape, such as peel off strength, adhesion strength, peel off angle, etc. And peel off strength is the mostly used method because it is also the simplest. We fix the sample tape with clamps on the multi-functional testing machine, and set the testing speed and angle. Then the tape will be peeled off in vertical or horizontal direction. We will get the data of force and testing time through which peel off strength can be calculated.
Adhesion strength is a kind of test when we apply the sample tape to the surface of metal or glass, then put certain load on it and keep it for certain amount of time. Then we test the force of different tape samples to evaluate of the adhesion accordingly.
Peel off angle is a kind of test when we apply the sample tape to a vertical surface and peel it off with a given angle. Then we can measure the angle generated through the process and get the final peel off angle.
The adhesion test result is related to different factors, such as the tape material, thickness, type of adhesive, coating area, and so on. Therefore, in order to keep the precision of the test results, we need to make sure the parameters are consistent, and there are control plans to keep the consistence. Besides, we can also test the wear resistance, temperature resistance, corrosion resistance, etc. through the manufacturing process to better evaluate the overall quality of the products.
Q: Why should we test the tape adhesion?
A: Adhesion is a key indicator of the quality and application performance of a tape. For certain process and products which need tapes, the adhesion of tape can affect the quality and reliability of the products.
Q: What methods are used to test the adhesion of a tape?
A: The testing methods normally used include peel off strength, adhesion strength, peel off angle, etc. Different methods are used to test different types of tapes and meet different testing demands.
Q: What factors are related to the adhesion of tapes?
A: The adhesion of a tape is related to factors such as tape material, thickness, surface treatment, type of adhesive, coating area, and so on. All of these factors can affect the adhesion of a tape.
