MP mixed with color masterbatch uneven color
Fenómeno del problema
MP/color masterbatch injection molded products show color streaks and regions of varying color depth
Análisis de la causa
color masterbatch carrier resin incompatible with MP; color masterbatch poorly dispersed, pigment agglomerated; unstable melt flow during '2079851475616104452 causes pigment orientation
Solución
1) select color masterbatch with MP or a similar carrier 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
Conclusión clave
color masterbatch carrier matching and full dispersion are key to color uniformity
