POM has excellent creep resistance but is notch sensitive
ظاهرة المشكلة
Although POM is creep resistant, its notched impact strength is low.
تحليل الأسباب
POM has regular molecular chains and high crystallinity, but the stress concentration effect at notches is obvious and the impact is low.
الحل
Avoid sharp corners and notches in design; fillet transitions; use toughened POM grades.
الخلاصة الأساسية
POM notch sensitivity is a design safety factor requirement.
