EMA stress cracking
Sorun Belirtisi
EMA products crack within <100h under stress + chemicals
Neden Analizi
Under stress, EMA molecular chains are attacked accelerated by chemicals; environmental stress cracking is a typical failure mode of polyolefins
Çözüm
1) Reduce product internal stress by annealing treatment; 2) Select high molecular weight EMA to improve ESC resistance; 3) Avoid contact with aggressive chemicals
Temel Çıkarım
Stress cracking is caused by stress-accelerated chemical attack; annealing and high MW are key
