Product Description:

Ranbar Red P1240, C.I. Pigment Red 144, is a semi-transparent blue-red azo condensation pigment. It exhibits a bright and vivid color, with extremely high coloring power. It possesses outstanding dispersibility and excellent colorfastness properties, including lightfastness, heat stability, migration resistance, solvent resistance, and acid-alkali resistance.

Ranbar Red P1240 Azo condensation pigment demonstrates exceptional migration resistance in flexible PVC (polyvinyl chloride) and maintains heat resistance up to 300°C in HDPE. It is important to note that this organic pigment exhibits relatively higher warping tendencies in HDPE.

 

Applications:
Ranbar Red P1240 is a versatile blue-red organic pigment widely used for coloring in the plastic, coating, and printing ink industries. It is recommended for use in polyvinyl chloride (PVC), polystyrene, polyurethane, styrene-based engineering plastics, elastomers, or cast resins, including plastics made from unsaturated polyester. Its excellent thermal stability and light resistance make it a suitable choice for polypropylene fiber dyeing. It is also recommended for various high-end printing inks, metal decorative inks, and can be used in architectural decorative coatings, powder coatings, and industrial coatings, among others.
