PRODUCT PROFILE
P.O.34Pigment Orange 34 — grade profile
Pigment Orange 34 (P.O.34) is a disazo pyrazolone pigment for Plastics & masterbatch, Printing inks and Coatings & paint. Compare shade, tinting strength, dispersion and processing stability in the customer’s actual resin or binder rather than relying on one universal value.
Published screening data includes published heat reference 200 °C, light fastness 6/8 and oil absorption 40–50 ml/100g. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include PVC, Polyolefins (PO), Offset inks, Water-based inks, Powder coatings and Water-based decorative coatings; NC inks and Solvent-based decorative coatings are listed for evaluation.
Selection focus
At equal loading, compare shade, tinting strength, dispersion and resin or binder compatibility, then confirm the required fastness under the final process conditions.
