Poor dispersion of PET color masterbatch
ظاهرة المشكلة
PET products colored with color masterbatch show uneven color depth, with color streaks or spots.
تحليل الأسباب
The carrier resin of the color masterbatch is incompatible with PET; the addition amount is insufficient or mixing is uneven; screw mixing effect is poor.
الحل
Use PET-based color masterbatch (carrier consistent with the matrix); add a static mixer; optimize the screw mixing section design.
الخلاصة الأساسية
PET coloring uniformity requires the color masterbatch carrier to match the matrix resin.
