Is Pigment Blue 15 a single product or a group of grades?

Pigment Blue 15 is a family of copper phthalocyanine grades rather than one single product. Different crystal forms and surface treatments are available, including alpha and beta modifications, which differ in shade, heat stability, and suitability for coatings, plastics, or inks.

What is the difference between alpha and beta Phthalocyanine Blue?

Alpha copper phthalocyanine typically gives a redder blue shade and may require stabilization for certain systems. Beta copper phthalocyanine, such as Pigment Blue 15:3, is generally more stable and is commonly preferred for plastics and higher-temperature processing.

Can Phthalocyanine Blue be used in plastics?

Yes. Pigment Blue 15 is widely used in plastics such as PVC, PE, PP, and engineering resins. Grade selection should match the resin, processing temperature, dispersion method, and required fastness properties.

What supply forms are available for Pigment Blue 15?

It is commonly supplied as dry powder or presscake. Powder grades are used for dry blending and masterbatch or ink production, while presscake grades are convenient for water-based and wet pigment processing systems.
