Fenómeno do problema
Glass Fibre/color masterbatch injection molded product shows color streaks and areas of varying color depth
Análise das causas
Color masterbatch carrier resin incompatible with Glass Fibre; color masterbatch poorly dispersed, pigment agglomerated; melt flow unstable during '2079851475616104452 causing pigment orientation
Solução
1) Select Glass Fibre or similar-carrier color masterbatch to ensure compatibility; 2) twin-screw extrusion pelletizing 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
