Stress cracking of EAA
ظاهرة المشكلة
The cracking time of EAA products under the action of stress + chemicals is <100h
تحليل الأسباب
Under stress, the molecular chains of EAA are attacked by chemicals at an accelerated rate; environmental stress cracking is a typical failure mode of polyolefins
الحل
1) Reduce the internal stress of the product by annealing treatment; 2) Select high molecular weight EAA to improve ESC resistance; 3) Avoid contact with aggressive chemicals
الخلاصة الأساسية
Stress cracking is caused by stress-accelerated chemical attack; annealing and high MW are the key
