Color Difference/Unstable Color of Cast Polypropylene Film ABS Products
Problem Phenomenon
The color of ABS products is unstable, and color differences appear between different batches or within the same batch, affecting product appearance consistency.
Cause Analysis
(1) The color masterbatch is poorly dispersed
(2) Processing temperature fluctuations cause 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
Solution
(1) Use a color masterbatch with good dispersibility
(2) Stabilize the processing temperature within the range of 230-270°C
(3) Unify the regrind ratio
(4) Use raw materials from the same batch
(5) Use a mixing-type screw
Key Takeaway
ABS color difference is caused by uneven pigment dispersion and process fluctuations.
