Color difference/unstable color of high impact polystyrene ABS products
Sorun Belirtisi
ABS product color is unstable, color difference appears between different batches or within the same batch, affecting product appearance consistency.
Neden Analizi
(1) Poor dispersion of color masterbatch particles
(2) Processing temperature fluctuation causes different pigment dispersion
(3) Inconsistent regrind ratio
(4) Different raw material base colors
(5) Insufficient screw shear
Çözüm
(1) Use color masterbatch particles with good dispersibility
(2) Stabilize processing temperature within the 180-240°C range
(3) Unify regrind ratio
(4) Use raw material from the same batch
(5) Use a mixing-type screw
Temel Çıkarım
ABS color difference is caused by uneven pigment dispersion and process fluctuation.
