Large EMA compression set
Fenómeno del problema
EMA product compression set >30%, below the 15% requirement
Análisis de la causa
EMA elastic recovery insufficient; crosslinking degree too low with unrecoverable plastic deformation; density too low with thin cell walls and poor recovery
Solución
1) Increase crosslinking degree to 60-70% to reduce plastic deformation; 2) Select high elastic recovery EMA grade; 3) Add reinforcing filler
Conclusión clave
Large compression set is caused by insufficient crosslinking; increasing crosslinking degree is key
