MP stress cracking
Problembeschreibung
MP products crack in <100h under stress + chemicals
Ursachenanalyse
under stress, MP molecular chains are accelerated attacked by chemicals; environmental stress cracking is a typical failure mode of polyolefins
Lösung
1) reduce product internal stress by annealing; 2) select high molecular weight MP to improve ESC resistance; 3) avoid contact with aggressive chemicals
Wichtigste Erkenntnis
stress cracking is caused by stress-accelerated chemical attack; annealing and high MW are key
