Tear propagation strength

The tear propagation test is used to establish structural strength.

The test is carried out to DIN ISO 34-1Bb on angled test specimens with an incision. These are pulled, perpendicular to the incision, at a velocity of 500 mm/min until they are torn apart. The tear propagation strength [kN/m] is the quotient of the highest force attained and the specimen thickness.

Results of the test method: Tear propagation strength [kN/m specimen thickness]

Desmopan® is far superior to most plastics in terms of its tear propagation strength.
