POE film moisture barrier insufficient
Problembeschreibung
POE WVTR>20g/m²·24h, below the <5 requirement
Ursachenanalyse
POE octene branches increase intermolecular spacing, promoting water vapor transmission
Lösung
1) Thicken 0.1-0.15mm to reduce WVTR; 2) POE/HDPE co-extrusion; 3) PVDC coating
Wichtigste Erkenntnis
POE moisture barrier insufficiency requires thickening, co-extrusion and coating to improve
