Poor dispersion of PET color masterbatch
문제 현상
PET products colored with color masterbatch show uneven color depth, with color streaks or spots.
원인 분석
The carrier resin of the color masterbatch is incompatible with PET; the addition amount is insufficient or mixing is uneven; screw mixing effect is poor.
해결 방법
Use PET-based color masterbatch (carrier consistent with the matrix); add a static mixer; optimize the screw mixing section design.
핵심 요약
PET coloring uniformity requires the color masterbatch carrier to match the matrix resin.
