Large EVOH Creep Deformation
Sorun Belirtisi
EVOH product creep under long-term load >5%, exceeding the 2% requirement
Neden Analizi
EVOH elastomer nature has large creep; molecular weight too low, creep resistance poor; not crosslinked, plastic flow large
Çözüm
1) Select high molecular weight grade; 2) Slight crosslinking 0.3wt% DCP to reduce plastic flow; 3) Add rigid filler to reduce creep
Temel Çıkarım
Large creep is caused by elastomer nature; slight crosslinking and rigid filler are key
