POE creep deformation large
문제 현상
POE product creep >5% under long-term load, exceeding 2% requirement
원인 분석
POE elastomer nature has large creep; molecular weight low, creep resistance poor; not crosslinked, large plastic flow
해결 방법
1) Select high molecular weight grade; 2) Slight crosslinking 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
