DSTDP surface blooming exudation
Problem Phenomenon
DSTDP product surface exudes white frost-like low-molecular substances, affecting appearance
Cause Analysis
Low-molecular components in DSTDP migrate to the surface and exude during storage; lubricant or plasticizer supersaturated exudation
Solution
1) Select high molecular weight DSTDP to reduce low-molecular substances; 2) reduce lubricant addition to a reasonable level; 3) clean the product surface and then detect the source
Key Takeaway
Blooming is caused by low-molecular migration and exudation; selecting high molecular weight grades is fundamental
