Sorun Belirtisi
Color masterbatch disperses poorly in the product, producing color spots and stripes.
Neden Analizi
The color masterbatch carrier resin (such as PE) is incompatible with PETG, and the dispersed phase is coarse.
Çözüm
Select PETG-based color masterbatch; use liquid color masterbatch or high-concentration color masterbatch; increase screw mixing.
Temel Çıkarım
PETG uniform coloring requires color masterbatch with a matching carrier.
