Ursachenanalyse
HDPE is prone to environmental stress cracking in media such as surfactants; it starts first at areas with high internal stress, and the ESCR resistance of grades varies greatly.
Lösung
①Select ESCR-resistant grades according to the medium (high MFR control/comonomer modification); ②reduce product internal stress; ③conduct medium immersion verification; ④avoid sharp corners and interference fit assembly.
Wichtigste Erkenntnis
HDPE holding chemicals, ESCR verification cannot be skipped.
