Explore our highly-stable chemical dyes formulated for diverse industrial substrates, from textiles and leather to paper shading and specialized plastic processing.
Technical classification, chemical performance data, and industrial criteria for high-precision manufacturing.
Pigment Green 7, chemically recognized as Copper Phthalocyanine Green, is a highly chlorinated organic pigment characterized by its brilliant green shade and exceptional durability. The chemical formula \(C_{32}Cl_{16}CuN_8\) describes a synthetic complex where hydrogen atoms in copper phthalocyanine are replaced by chlorine atoms. This precise chemical composition grants the pigment its unmatched resistance to light, heat, chemical corrosion, and weathering solvents.
For B2B procurement managers and plant engineers, Pigment Green 7 is the industry standard for applications demanding strict color consistency. It shows zero migration in polymeric structures and remains thermally stable up to 300°C, making it the primary green colorant for plastic masterbatches, powder coatings, high-performance automotive paints, and printing inks.
Our factories leverage advanced synthesis pathways to control molecular morphology, ensuring optimized dispersion and minimizing filter pressure values (FPV) during masterbatch extrusion. By partnering with Sunrise, you gain access to an optimized supply chain that delivers custom particle distributions matching your exact process parameters.
