PETG '2079851475616104452 color masterbatch carrier mismatch causing spots
Fenómeno do problema
Color masterbatch disperses poorly in the product, producing color spots and stripes.
Análise das causas
The color masterbatch carrier resin (such as PE) is incompatible with PETG, and the dispersed phase is coarse.
Solução
Select PETG-based color masterbatch; use liquid color masterbatch or high-concentration color masterbatch; increase screw mixing.
Conclusão principal
PETG uniform coloring requires color masterbatch with a matching carrier.
