MP surface blooming exudation
Problembeschreibung
MP product surface exudes white frost-like low molecular species, affecting appearance
Ursachenanalyse
low molecular components in MP migrate to the surface and exude during storage; lubricant or plasticizer supersaturated exudation
Lösung
1) select high molecular weight MP to reduce low molecular species; 2) reduce lubricant addition to a reasonable level; 3) clean the product surface then test the source
Wichtigste Erkenntnis
blooming is caused by low molecular migration exudation; selecting a high molecular weight grade is fundamental
