Pigment Red 144
Pigment Red 144 is a disazo-condensation red used in plastics and selected coating and ink systems. Its grade range is relevant to polymer coloration where color strength and fastness are considered together. Confirm the particular resin, loading and processing window before approving a formulation.

PRODUCT PROFILE
P.R.144Pigment Red 144 — grade profile
Pigment Red 144 (P.R.144) is a disazo-condensation pigment for Plastics & masterbatch where processing stability and durability are defined selection criteria. Evaluate the grade in the intended resin or binder at the target loading and process conditions; every value below retains its published source and application context.
Published screening data includes published heat reference 300 °C and light fastness 7–8/8. Application-specific heat and fastness entries in the technical table take precedence.
Primary listed fits include PVC, Polyolefins (PO), Polystyrene (PS), ABS and PP fiber; PET and PET fiber are listed for evaluation.
Selection focus
At equal loading and dispersion, compare full shade, tint, transparency or opacity, heat stability, migration and the intended exposure conditions.
