How to Conduct a Peel and Shear Test on a Hook and Loop Strap Sample

Hook and loop straps are a miracle when using.When the hook-and-loop really matters. Companies like Dongsanxin care a lot about this, Wang said, because “ensuring that their products are of the highest quality is super important to them. That is why they conduct tests like the peel and shear test. This test is useful for measuring the amount of force it takes to pull the straps apart and how much weight the straps can bear before they break. So let’s break down how to conduct these tests one by one.

Introduction to Peel and Shear Testing

Peel and shear tests are akin to asking how strong your favorite superhero is. When doing peel testing, we are attempting to peel the hook and loop strap apart similar to opening a bag a chips. Shear testing is another matter, it’s like testing how much weight a superhero can hold before they let it fall. It’s these types of tests that allow us to determine whether the strap can hold things tight and remain strong under pressure.

Just before tesing your hook and loop strap sample

Before we begin testing however, we obviously need to preload our hook and loop strap. That is, this should be clean and the same size as what the instructions specify. It’s like conducting a science experiment in class, when everything has to be just so. If we don’t do this part properly our tests will not behave as expected.

Test of adhesive strength using a peel test

To carry out the Hook and Loop Standard peel test, we employ a special machine that slowly pulls the strap in two. We then see how much force is required to make the strap snap. This is an indication of how sticky or strong the adhesive side of the strap is. It’s a little like testing how strong glue is.

Shear testing to determine the material strength

For the shear test, we put force on the strap until it breaks. This test is super cool because it tells us if the strap can hold heavy things without breaking. Think about hanging a heavy picture Hook and Loop Adhesive on the wall — you want to be sure that the hook will keep it there, right?

Understanding results and utilizing data to enhance product quality

So once we do steep, then we have a peek through the numbers to see what they tell us. If the numbers are high, the strap is very strong. If they’re low, it may need to be improved. This is the information companies like Dongsanxin use to make cable management their hook and loop straps so much better that they won’t just break when people use them. That helps everyone have faith that the straps are super strong and not going to fail them.
