Elongation at break 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 elongation at break of rubber.


What is the elongation at break of rubber?

The elongation at break is the extent a rubber material can be strained (%), before it breaks. We apply tensile force and stretch the material. A percentage of the original lenght is used to express the elongation at break. It is typically in the order of 100-600%, and some examples even go up to 1000%. When the rubber ruptures, we have found the ultimate elongation.

What is measured while determining the elongation (ISO 37)?

The determination of the tensile properties gives more results than only the elongation, such as the following rubber properties:

How do we test the stress-strain properties of rubber?

We can test the stress-strain properties (tensile strength, elongation at break, and stiffness), both at standard laboratory temperature (SLT, 23±2°C) and at application-specific elevated temperatures up to 275°C. All properties of rubber are generally determined based on ASTM, DIN, EN, or ISO standards.
