EEA Surface Blooming
Fenómeno do problema
White frost-like low-molecular substances exude on the surface of EEA products, affecting appearance
Análise das causas
Low-molecular components in EEA migrate to the surface and exude during storage; lubricant or plasticizer supersaturated exudation
Solução
1) Select high-molecular-weight EEA to reduce low-molecular substances; 2) Reduce lubricant addition to a reasonable level; 3) Clean the product surface and then detect the source
Conclusão principal
Blooming is caused by low-molecular migration and exudation; selecting a high-molecular-weight grade is fundamental
