The PET release film (or release paper test) test is divided into several parts: standing test, 20 minutes at room temperature, 24 hours at room temperature, 24 hours aging, residual force, dry silicon content and the most important part of data storage. Such as determining the test equipment: vertical tensile machine. There are also horizontal tensile machines on the market, but the price is too expensive, and the test force is small, and the ratio used is small. There will be some data differences between the vertical tensile machine and the horizontal tensile machine when measuring the same release film. Therefore, when someone says that his test data is different from yours, you can first ask what type of tensile machine is? In fact, the test of the same model of tensile machine will be different. One is that the machine itself has errors. In addition, the tension head will be different. The difference lies in the maximum tension value of the tension head. At present, the maximum tensile force of common tensile heads on the market is 1kg, 2kg, 5kg, and 10kg. If you use 1kg to measure within 1000G, it is definitely more accurate than 10kg. Therefore, this is also something that many people overlook. It is more accurate to change the tension head to the lighter one.
