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 / pull-off test

Peel resistance is measured during a pull-off test. Because the resistance largely depends on the peel angle, the standard has produced a number of different test methods. ZwickRoell offers the right test fixture for each method.

90° pull-off test
180° pull-off test
Roll peel test
Sealed seam test

Initial adhesion

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.

ZwickRoell test tools and application examples

90° pull-off test

To measure the peel resistance

90° peel test kit for adhesive tape

For adhesion tests on glued connections with a stiff base (3 mm to 50 mm thick) and a flexible top layer (up to 20 mm).

Sealed seam test device

Testing of seal seams on a yogurt cup The peel angle remains constant.

Unrolling unit for adhesive tape

Unwind adhesion measurement of adhesive bondings

Loop tack test: initial stickiness or application tack of test strips on interchangeable plates, e.g., according to the Finat test method no. 9

Adhesive tape loop tack test

Testing the adhesive force when peeling test strips off interchangeable plates to determine the initial stickiness or application tack, e.g. according to the Finat test method no. 9.
