EVA creep deformation is large
Sorun Belirtisi
EVA product creep under long-term load >5%, exceeding the 2% requirement
Neden Analizi
EVA elastomer nature has large creep; molecular weight too low with poor creep resistance; no crosslinking with large plastic flow
Çözüm
1) Select high molecular weight grade; 2) Slight crosslinking with 0.3wt% DCP to reduce plastic flow; 3) Add rigid fillers to reduce creep
Temel Çıkarım
Large creep is caused by the elastomer nature; slight crosslinking and rigid filler are key
