EVA fatigue resistance is poor
Fenómeno del problema
EVA product fatigue life <10⁴ cycles, below the 10⁵ cycle requirement
Análisis de la causa
EVA elastic recovery insufficient, accumulating plastic deformation each cycle; crosslinking degree too low with fast fatigue crack propagation
Solución
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
Conclusión clave
Poor fatigue resistance is caused by insufficient recovery and fast crack propagation; increasing crosslinking is key
