Rebound resilience

What is rebound resilience?

Rebound resilience is a measure used to describe the damping of rubber components. It describes the percentage by which the test specimen differs from the
elastomer
is pushed back. A high value means a low attenuation. Flummis (rubber balls) are known in everyday life for a very high rebound elasticity.

It is measured by bouncing a steel ball on the rubber over a certain distance. The ratio of the initial distance to the rebound distance gives the rebound elasticity.

The test is specified in the DIN 53512 or ISO 4662 standard.

Natural rubber has by far the best rebound resilience. But EPDM, silicone and NBR are also suitable.

The ability to return to the starting position from a deformation is called
elasticity
is referred to as elasticity.
