Internal or external cracking of plastics caused by various stresses lower than the short-term mechanical strength of plastics.


This type of cracking is often accelerated by the environment in which the plastic is located, and the presence of external or internal stresses or a combination of both can cause cracking. Network - like cracks formed by small cracks also known as cracks.
