PIGMENT ORANGE 64 – Introduction and Application

PO64 is also called Fast Orange GP, it’s a bright reddish orange with high tint strength.

It needs 0.42% pigment to prepare 1/3 SD of HDPE with 2% titanium dioxide.

The light fastness of Pigment Orange 64 is good and reaches 7-8 grade in PVC (1/3 SD with 2% titanium dioxide). The heat resistance gets up to 260 °C/5min. It is applied not only to the coloring of polyolefin but also to the coloring of styrene engineering plastics. It is the typical color of HDPE pressured pipes. Owing to the high tint strength, high color saturation and excellent overall properties, Pigment Orange 64 may become a standard orange after a certain level of price decreasing.

PO64 is a Benzimidazolone pigment, which is a class of high-performance organic pigment, such as PY151, PY180, PO36 are all belong to this category. The molecular structure of PO64 contains an azo group, so it belongs to mono azo pigments, this type of pigments always has bright color and strong color strength.

In our QC lab, we use Polypropylene(PP) to do pigment color test. As shown by the picture, the left is full shade color, and the right one is tint shade. It obvious shows PO64 is a very bright reddish orange with high color strength.

As this table shows, PO64 has very excellent fastness for acid, alkali, water, oil, light and good weather resistance, heat resistance, solvent resistance.

FYI, here is the application properties of PO64 in PVC and HDPE.

When we add PO64 in HDPE, it can withstand 300℃ for 5 minutes. But as the temperature increasing, the color shade will become yellowish, but it doesn’t affect the crystallinity of the polymer, or lead to dimensional deformation.

Because of its excellent color strength, heat stability and light fastness, PO64 becomes the industry standard for high performance oranges. it suitable for printing ink, paints, plastic such as PVC, LDPE, HDPE, PP, PU, ABS, PP Fiber, Rubber, etc.

It is widely used in many fields. Most of our customers are used to making masterbatch firstly, then producing different kinds of plastic products such as pipes ，cables and wires. PO64 is the standard colors of HDPE pressure pipes, Of course, some manufactures like using it in inks, painting, coating.

Our PO64 can comply with international regulations, like REACH, EN71-3, AP89-1.

In summary, PO64 is a bright red shade organic orange pigment. It has become the industry standard for high performance oranges. It suitable for virtually all polymers and applications including food contact and toys, FDA listed and in French Positive List.
