Environmental Stress Cracking

Environmental stress cracking is one of the most common causes of unexpected brittle failure of polymers known. This is why industries such as aerospace and packaging need to understand the environmental stress cracking resistance of plastics and polymers.

Carrying out environmental stress cracking tests with equipment like the Ray-Ran Environmental Stress Cracking Apparatus enables them to determine the time it takes for the materials to develop cracks and eventual catastrophic failure when subjected to constant stress concentrations (in the form of liquid or vapour).

We also specialise in environmental testing equipment calibration for a wide variety of equipment, including environmental chambers, salt spray test chambers, and battery test chambers.
