Large EMA creep deformation

문제 현상

EMA product creep >5% under long-term load, exceeding the 2% requirement

원인 분석

EMA elastomer nature with large creep; molecular weight too low with poor creep resistance; no crosslinking with 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 elastomer nature; slight crosslinking and rigid filler are key

EMA creep slight crosslinking high molecular weight rigid filler
