EMA surface blooming
ظاهرة المشكلة
White frost-like low molecular substances exude on EMA product surface, affecting appearance
تحليل الأسباب
Low molecular components in EMA migrate to the surface and exude during storage; lubricant or plasticizer supersaturation exudation
الحل
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
الخلاصة الأساسية
Blooming is caused by low molecular migration and exudation; selecting high molecular weight grade is fundamental
