zwickiLine for Flexible Low-Force Testing.
Tear growth tests
Tear strength describes the resistance of a material to the expansion of a tear. The test setup is similar to a tensile test. The specimen is a trouser specimen or angle specimen with a defined tear length.
Peel resistance tests
Peel resistance is measured during a pull-off test. Because the resistance depends significantly on the peel angle, the standard has produced a number of different test methods. ZwickRoell offers the right test fixture for each method.
This characteristic, also known as a contact adhesion, is determined, for example, for adhesive labels and tape. It describes the first adhesion, known as the "initial tack" in the form of the maximum peel strength.
