2.Application Characteristics
Primary Applications:
Plastics Coloring: The primary application. It is especially valued in Polyolefins like Polypropylene (PP) and High-Density Polyethylene (HDPE) due to its excellent heat resistance (often up to 200°C or higher), which is superior to the Calcium (48:2) and Barium (48:1) lakes. It also shows low warping in polyolefins.
Inks: Used in specific ink applications where its particular bluish shade and good rheology are required.
Coatings: Can be used in industrial coatings that require its specific coloristic properties.
Key Advantages:Bluish, clean red shade.
Superior heat resistance compared to other PR48 variants, making it suitable for engineering plastics.Good lightfastness for many applications.Low warpage in polyolefins.
