Source publication: 2026-10-22. Mascom’s October 22 technical review discusses NIR-detectable black masterbatch and tests processors should run before selecting a pigment.
What did the October 22 review discuss?
Vietnamese masterbatch producer Mascom published a technical review on October 22, 2026 covering trends in color masterbatch. One topic was specially formulated black masterbatch intended to remain detectable by near-infrared (NIR) plastic sorting systems. The company notes that conventional carbon black can interfere with identification of some black plastics. Its article is an industry perspective, not a certification of all black masterbatches or pigments.
Analysis
Color and processability during manufacture are separate from detectability at a recycling plant. NIR response depends on polymer, formulation, pigment concentration, part thickness and sorting equipment. Buyers requiring sortable packaging should test finished samples on the intended system rather than infer performance from color or a grade name. Dispersion, melt viscosity and finished-part properties must also be checked after processing. Gohar’s product descriptions alone do not establish NIR detectability.
What this means for pigment selection
For a black pigment option focused on processability in polymer compounds, review Gohar P-80. No NIR-sorting claim is made for that grade; test the finished part. Gohar P-80 black pigment.
