ExcelPlas Labs Undertake Failure Analysis, Failure Diagnosis and Root Cause Identification for Polyethylene Pipes
Failure in HDPE pipes could happen over a long term under low stress (under the yield stress).
The resistance to this phenomenon is the environmental stress-cracking resistance or slow crack resistance (SCR).
The high SCR in bimodal PE is due to the chain entanglements obtained with the incorporation of comonomers in the polymer of the high molecular weight fraction.
These entanglement networks affect the overall mechanical behavior under low stress conditions.
The failure includes several stages:
Microscopic cavities are formed around inhomogeneities such as scratches, pigments, catalyst residues, fillers and then these cavities form the initiation crazing step. It takes the largest fraction of the failure  mechanism. Once the deformation zone is formed, crazes propagate by the disentanglement of macromolecules and plastic deformation (yielding) until a crack initiation.
