Stiffness of rubber

Elastomer Research Testing BV is an independent and ISO 17025 accredited research and test laboratory which offers a wide range of methods to determine rubber properties, such as the stiffness of rubber.


What is the stiffness of rubber?

The moduli of rubber are typically expressed as the stress needed to strain a rubber sample. This is measured for 25%, 50%, 100%, 200% and 300%, reported as Modulus 25%. The stiffer the material is, the higher the stress needed.


Determining the stiffness of rubber (ISO 37)

The determination of the tensile properties gives more results than only the stiffness of rubber. The following rubber properties are obtained:


Testing the stress-strain properties of rubber

Tests of stress strain properties can be performed at both standard laboratory temperature and at application-specific elevated temperatures. All properties of rubber are generally determined based on ASTM, DIN, EN, or ISO standards.
