문제 현상
EAA product surface precipitates white frost-like low molecular substances affecting appearance
원인 분석
Low molecular components in EAA migrate to the surface and precipitate during storage; lubricant or plasticizer supersaturated and precipitating
해결 방법
1) Select high molecular weight EAA to reduce low molecular substances; 2) Reduce lubricant addition to a reasonable level; 3) Clean the product surface and then test to identify the source
핵심 요약
Blooming is caused by low molecular migration and precipitation; selecting a high molecular weight grade is fundamental
