Large EMA compression set
Problembeschreibung
EMA product compression set >30%, below the 15% requirement
Ursachenanalyse
EMA elastic recovery insufficient; crosslinking degree too low with unrecoverable plastic deformation; density too low with thin cell walls and poor recovery
Lösung
1) Increase crosslinking degree to 60-70% to reduce plastic deformation; 2) Select high elastic recovery EMA grade; 3) Add reinforcing filler
Wichtigste Erkenntnis
Large compression set is caused by insufficient crosslinking; increasing crosslinking degree is key
