What Is Environmental Stress Cracking and How To Prevent It Webinar


Engineering plastics are widely used in chemical environments due to their broad resistance to aggressive media. Certain plastics are susceptible to environmental stress cracking (ESC), or premature brittle failure caused by the combination of stress and adverse environmental conditions. ESC is one of the most common causes of plastic part failure.

This webinar provides engineers and designers with an overview of ESC, plastic material selection, plastic part design, and assembly, in order to avoid costly part failures. Download the webinar slides.

Webinar topics include:

  • What is ESC and what causes it?
  • The time-dependency of thermoplastic mechanical properties
  • ESC as a form of accelerated creep rupture
  • ESC mechanism: initiation, propagation
  • Testing for ESC resistance
  • Preventing ESC - material selection, part design, and assembly considerations
  • Predictive methodologies and interpreting chemical resistance data
