The Finetech Engineering Pendulum Rebound Resilience Tester measures the elastic resilience of vulcanised rubber by striking a rubber specimen with a pendulum and measuring how high the pendulum rebounds. Resilience is the ability of rubber to return stored elastic energy after deformation – think of it as the material’s “bounce.” A tyre tread compound needs low resilience (high hysteresis) for grip. A ball needs high resilience for bounce. A vibration mount needs tuned resilience for damping.
To answer “what is rebound resilience rubber Schob pendulum” and “how is rebound resilience measured rubber pendulum”: a pendulum is released from a known angle, strikes the flat surface of a rubber specimen, and rebounds to a lower angle. The ratio of rebound height to drop height, expressed as a percentage, is the rebound resilience. A perfect elastic material would rebound to 100%. Real rubber compounds typically show 20–80% resilience depending on polymer type, filler loading, and temperature.
The ISO 4662 pendulum rebound tester India (also called the Schob pendulum or Lupke pendulum) is the most widely used rubber elasticity tester pendulum India in the rubber industry. It correlates well with dynamic mechanical properties and is used for compound development, batch QC, and material specification compliance.
Note: Rebound resilience is temperature-sensitive. Always test your rebound resilience tester rubber India specimens at the standard temperature (23°C ±2°C) unless your specification requires otherwise. A compound tested at 40°C will show higher resilience than the same compound at 23°C.

To answer “what is rebound resilience rubber Schob pendulum”: rebound resilience is the percentage of energy returned by a rubber specimen when struck by a pendulum. Higher resilience means the rubber is more elastic and returns more energy. Lower resilience means more energy is absorbed as heat. Typical values range from 20% (high-damping compounds like butyl rubber) to 80% (highly elastic compounds like natural rubber).
The pendulum vs vertical rebound rubber test difference: the pendulum rebound test uses a swinging pendulum that strikes a flat specimen horizontally; the vertical rebound test (ASTM D2632) drops a plunger vertically and measures the bounce height. Both measure resilience but by different methods. The pendulum method is preferred in ISO and DIN standards. The vertical method is a simpler ASTM option. Finetech manufactures both.
A flat rubber disc or button, minimum 29 mm diameter and 12.5 mm thick. This is the same specimen used for Shore A/D hardness testing. You can use the same hardness buttons from the Finetech hardness button mould.
ASTM D2632 recommends at least 3 impacts per specimen at different locations, and at least 3 specimens per sample. Report the median or mean.
On the question “is rebound resilience same as hardness rubber” – no. They are related but different. Hardness measures resistance to static indentation; resilience measures energy return under dynamic impact. A compound can be soft (low hardness) but highly resilient, or hard but poorly resilient.
Yes. The Finetech ISO 4662 pendulum rebound tester India meets NABL requirements. We provide calibration certificates for pendulum angle and release mechanism.
