Sorun Belirtisi
EMA/color masterbatch injection molded products show color streaks and areas of different color shades
Neden Analizi
Color masterbatch carrier resin incompatible with EMA; color masterbatch poorly dispersed, pigment agglomerates; unstable melt flow during '2079851475616104452 causes pigment orientation
Çözüm
1) Select EMA or similar carrier color masterbatch to ensure compatibility; 2) Twin-screw extrusion pelletizing for pre-dispersion; 3) Appropriately extend mixing time to ensure pigment dispersion; 4) Reduce injection speed to reduce pigment orientation
Temel Çıkarım
Color masterbatch carrier matching and full dispersion are the key to color uniformity
