EVA fatigue resistance is poor
문제 현상
EVA product fatigue life <10⁴ cycles, below the 10⁵ cycle requirement
원인 분석
EVA elastic recovery insufficient, accumulating plastic deformation each cycle; crosslinking degree too low with fast fatigue crack propagation
해결 방법
1) Increase crosslinking degree to improve recovery and reduce accumulated deformation; 2) Select high molecular weight grade to raise the fatigue threshold; 3) Product design to reduce stress concentration
핵심 요약
Poor fatigue resistance is caused by insufficient recovery and fast crack propagation; increasing crosslinking is key
