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
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
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.
180° peel test
To EN 1939 and AFERA 4001
Peel tests on composites
Adhesion tests on layers of plastic sheets and films according to DIN 53357 Method B (withdrawn), DIN 55543-5, etc.
Device for positioning and tracking flexible specimens
180° peel test for determination of adhesion forces (seal strength test)
