Color Difference/Unstable Color of acrylonitrile-butadiene-styrene copolymer ABS Products
문제 현상
The color of ABS products is unstable, and color difference appears between different batches or within the same batch, affecting product appearance consistency.
원인 분석
（1）The color masterbatch is poorly dispersed
（2）Processing temperature fluctuations lead to different pigment dispersion
（3）The regrind ratio is inconsistent
（4）The base colors of the raw materials are different
（5）The screw shear is insufficient
해결 방법
（1）Use color masterbatch with good dispersibility
（2）Stabilize the processing temperature within the 220-260°C range
（3）Unify the regrind ratio
（4）Use raw materials of the same batch
（5）Use a mixing-type screw
핵심 요약
ABS color difference is caused by uneven pigment dispersion and process fluctuations.
