Tensile force measuring instrument

The pull-off adhesion tester measures the force required to break an adhesive bond by adhering a sample to a substrate and a test head, then pulling them apart vertically at a constant speed. It is used to evaluate the adhesion of coatings, adhesives, and other materials, and is commonly employed in quality control within industries such as paints and plastics.
Selection
When selecting a tensile testing machine, consider matching the maximum tensile force range with the sample strength, ensuring precision meets testing standards, compatibility of fixtures with the sample shape and size, ease of operation, as well as equipment durability and maintenance costs.
