Large EAA creep deformation
문제 현상
EAA products under long-term load show creep >5% exceeding the 2% requirement
원인 분석
EAA elastomer nature has large creep; molecular weight too low, poor creep resistance; not crosslinked, large plastic flow
해결 방법
1) Select high molecular weight grade; 2) Slight crosslinking with 0.3wt% DCP to reduce plastic flow; 3) Add rigid filler to reduce creep
핵심 요약
Large creep is caused by the elastomer nature; slight crosslinking and rigid filler are key
