Tear strength & tear propagation resistance
Tear resistance is a measurement that shows how quickly cracks occur in the material.
Tear resistance is a measurement that shows how quickly the already present cracks tear propage and ultimately make the product unusable.
Both parameters have a major impact on the wear behaviour of the material.
Vulkollan® has a very good tear resistance as an elastomer material.
This property, together with its high elasticity, make Vulkollan® the benchmark material for low wear in dry and wet friction.
Only fibre reinforced plastics have a tear-propagation resistance of the same level. In mechanical engineering, this property differentiates in wear-sensitive parts such as scrapers, cutting tools and drive wheels.
