Large EMA creep deformation
Sorun Belirtisi
EMA product creep >5% under long-term load, exceeding the 2% requirement
Neden Analizi
EMA elastomer nature with 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 filler to reduce creep
Temel Çıkarım
Large creep is caused by elastomer nature; slight crosslinking and rigid filler are key
