Insufficient EVOH Tensile Strength
Problembeschreibung
EVOH product tensile strength 15-20% below standard value
Ursachenanalyse
EVOH molecular weight too low, strength foundation insufficient; filler interface poor, no reinforcing effect; orientation excessive, strong longitudinally and weak transversely
Lösung
1) Select high molecular weight EVOH grade; 2) Treat filler with coupling agent to improve interface; 3) Reduce orientation to decrease longitudinal-transverse difference
Wichtigste Erkenntnis
Insufficient tensile strength is caused by molecular weight and poor interface; selecting high MW grade is key
