POM has excellent creep resistance but is notch sensitive
Problembeschreibung
Although POM is creep resistant, its notched impact strength is low.
Ursachenanalyse
POM has regular molecular chains and high crystallinity, but the stress concentration effect at notches is obvious and the impact is low.
Lösung
Avoid sharp corners and notches in design; fillet transitions; use toughened POM grades.
Wichtigste Erkenntnis
POM notch sensitivity is a design safety factor requirement.
