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