Insufficient EAA tensile strength
Problembeschreibung
EAA product tensile strength 15-20% below standard value
Ursachenanalyse
EAA molecular weight too low, insufficient strength foundation; poor filler interface not providing reinforcement; excessive orientation, strong longitudinally and weak transversely
Lösung
1) Select high molecular weight EAA grade; 2) Treat filler with coupling agent to improve interface; 3) Reduce orientation to reduce longitudinal-transverse difference
Wichtigste Erkenntnis
Insufficient tensile strength is caused by molecular weight and poor interface; selecting high MW grade is key
