DSTDP and color masterbatch mixing uneven color
Sorun Belirtisi
DSTDP/color masterbatch injection molded products show color streaks and regions of uneven color depth
Neden Analizi
Color masterbatch carrier resin incompatible with DSTDP; poor color masterbatch dispersion, pigment agglomeration; unstable melt flow during '2079851475616104452 causing pigment orientation
Çözüm
1) Select DSTDP or same-type 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
Temel Çıkarım
Color masterbatch carrier matching and sufficient dispersion are the key to color uniformity
