POE and color masterbatch mixing color uneven
Fenómeno do problema
POE/color masterbatch injection molded products show color streaks and areas of uneven color depth
Análise das causas
Color masterbatch carrier resin incompatible with POE; color masterbatch poorly dispersed, pigment agglomeration; unstable melt flow during '2079851475616104452 causes pigment orientation
Solução
1) Select POE or same-type carrier color masterbatch to ensure compatibility; 2) Twin-screw extrusion granulation pre-dispersion; 3) Appropriately extend mixing time to ensure pigment dispersion; 4) Reduce injection speed to reduce pigment orientation
Conclusão principal
Color masterbatch carrier matching and full dispersion are the key to color uniformity
