Large PVA creep deformation
문제 현상
PVA product creep under long-term load >5%, exceeding the 2% requirement
원인 분석
PVA elastomer nature has large creep; molecular weight on the low side, poor creep resistance; no crosslinking, 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 the elastomer nature; slight crosslinking and rigid filler are the key
