EEA Stress Cracking
문제 현상
EEA products crack in <100h under the action of stress + chemicals
원인 분석
Under stress, EEA molecular chains are attacked accelerated by chemicals; environmental stress cracking is a typical failure mode of polyolefins
해결 방법
1) Reduce product internal stress by annealing treatment; 2) Select high-molecular-weight EEA to improve ESC resistance; 3) Avoid contact with aggressive chemicals
핵심 요약
Stress cracking is caused by stress-accelerated chemical attack; annealing and high MW are key
