What Is Environmental Stress Cracking and How To Prevent It

Engineering plastics are used in chemical environments due to their broad resistance to aggressive media. Environmental stress cracking (ESC) is one of the most common causes of plastic part failure.

This webinar provides engineers and designers with an overview of ESC (premature brittle failure caused by the combination of stress and adverse environmental conditions), plastic material selection, plastic part design, and assembly, in order to avoid costly part failures.

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
