Carbon black is widely used due to its strong tinting strength and low cost. However, in many industrial applications, color strength alone is not the primary performance requirement. Thermal stability, chemical resistance, and long-term color durability can be more critical.
Carbon black is composed of elemental carbon with high surface area. While effective for coloration, it can suffer from oxidation, color drift, and conductivity-related side effects at elevated temperatures.
Copper chromite black is an inorganic spinel pigment with a stable crystal structure. It is designed for high-temperature and chemically aggressive environments where organic carbon pigments degrade.
Copper chromite black maintains color stability during high-temperature processing, such as plastics compounding and ceramic firing, where carbon black may oxidize or discolor.
Inorganic spinel pigments show superior resistance to acids, alkalis, and weathering, making them suitable for long-life outdoor or chemically exposed applications.
Unlike carbon black, copper chromite black does not introduce unintended electrical conductivity, which is critical in insulating or dielectric applications.
Copper chromite black should be selected when thermal stability, chemical resistance, and electrical insulation are more important than maximum tinting strength. It is a functional pigment choice rather than a purely color-driven one.
