EAA surface blooming
Sorun Belirtisi
EAA product surface precipitates white frost-like low molecular substances affecting appearance
Neden Analizi
Low molecular components in EAA migrate to the surface and precipitate during storage; lubricant or plasticizer supersaturated and precipitating
Çözüm
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
Temel Çıkarım
Blooming is caused by low molecular migration and precipitation; selecting a high molecular weight grade is fundamental
