Stress Cracking of CMC
Problembeschreibung
CMC products crack in <100h under stress + chemicals
Ursachenanalyse
Under stress, CMC molecular chains are attacked by chemicals at an accelerated rate; environmental stress cracking is a typical failure mode of polyolefins
Lösung
1)Reduce product internal stress by annealing treatment; 2)Select high-molecular-weight CMC 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 the key
