CEF stress cracking
문제 현상
The CEF product cracks under stress + chemicals within <100h
원인 분석
The molecular chains of CEF under stress are attacked and accelerated by chemicals; environmental stress cracking is a typical failure mode of polyolefins
해결 방법
1) Reduce the internal stress of the product by annealing treatment; 2) Select high-molecular-weight CEF 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 the key
