원인 분석
Low molecular components in EMA migrate to the surface and exude during storage; lubricant or plasticizer supersaturation exudation
해결 방법
1) Select high molecular weight EMA 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
