PETG color migration during dyeing
ظاهرة المشكلة
The color of PETG products migrates to contacted objects (packaging paper, other plastics), causing contamination.
تحليل الأسباب
The dye or pigment used has poor migration resistance, residual low-molecular substances carry the color migration, and the processing temperature is insufficient to fully fix it.
الحل
Select migration-resistant pigments instead of dyes; increase the processing temperature for full dispersion and fixation; seal-coat the product surface.
الخلاصة الأساسية
PETG color migration is closely related to colorant selection.
