CEF surface blooming and exudation
Problem Phenomenon
White frost-like low-molecular substances exude on the surface of the CEF product, affecting the appearance
Cause Analysis
The low-molecular components in CEF migrate to the surface and exude during storage; lubricants or plasticizers are supersaturated and exude
Solution
1) Select high-molecular-weight CEF to reduce low-molecular substances; 2) Reduce the amount of lubricant added to a reasonable level; 3) Clean the surface of the product and detect the source
Key Takeaway
Blooming is caused by low-molecular migration and exudation; selecting high-molecular-weight grades is fundamental
