Influence of micromolecular structure on environmental stress cracking resistance of high density polyethylene
Highlights ► Study focuses on how micromolecular structure characteristics influence ESCR of HDPE. ► An improved and faster method for evaluating ESCR of PE is suggested. ► The new method is based on hardening stiffness in tensile deformation. ► Practical prescriptions are offered for evaluation and selection of better ESCR resins.
Abstract Environmental stress cracking (ESC) is a serious problem for polyethylene (PE) in structural applications and can result in catastrophic failure without any visible warning. Due to the nature of polymeric materials, polyethylene with excellent short-term mechanical strength can have poor long-term performance due to environmental stress cracking. In this work, we present our recent research findings on environmental stress cracking resistance (ESCR) of polyethylene. In this comprehensive overview we discuss (1) molecular structure influences on ESCR, (2) a new method for evaluating ESCR of PE, and (3) ESC modeling work, practical tips and prescriptions for producing and choosing better (higher) ESCR pipe material.
