POM has excellent creep resistance but is notch sensitive
Fenómeno do problema
Although POM is creep resistant, its notched impact strength is low.
Análise das causas
POM has regular molecular chains and high crystallinity, but the stress concentration effect at notches is obvious and the impact is low.
Solução
Avoid sharp corners and notches in design; fillet transitions; use toughened POM grades.
Conclusão principal
POM notch sensitivity is a design safety factor requirement.
