POE fatigue resistance poor
Sorun Belirtisi
POE product fatigue life <10⁴ cycles, below 10⁵ cycles requirement
Neden Analizi
POE elastic recovery insufficient, each cycle accumulates plastic deformation; crosslinking degree low, fatigue crack propagates fast
Çözüm
1) Increase crosslinking degree to improve recovery and reduce accumulated deformation; 2) Select high molecular weight grade to raise fatigue threshold; 3) Product design to reduce stress concentration
Temel Çıkarım
Poor fatigue resistance is caused by insufficient recovery and fast crack propagation; increasing crosslinking is key
