Q1: What is the primary chemical class and structural characteristic of BASF K8730?
A: BASF K8730 is a copper phthalocyanine-based pigment, characterized by its highly conjugated macrocyclic structure, which delivers exceptional lightfastness, thermal stability, and intense blue-green hue. It is supplied in a chemically stable, non-sulfonated form optimized for organic solvent-based and high-performance polymer systems.
Q2: Is BASF K8730 suitable for use in food-contact plastics or inks?
A: BASF K8730 is not pre-qualified for direct food-contact applications under global regulatory frameworks. Its suitability depends on final formulation compliance, migration testing, and end-use conditions. Customers must conduct full regulatory assessment—including extractables profiling and application-specific risk evaluation—prior to use in food-contact materials.
Q3: How does BASF K8730 perform in high-temperature processing environments, such as injection molding or extrusion?
A: Due to its robust crystalline structure and high decomposition onset, BASF K8730 exhibits excellent thermal stability and retains color strength and dispersion integrity at typical polymer processing temperatures up to 280 °C. Performance may vary depending on residence time, shear history, and resin compatibility—pre-dispersed masterbatches are recommended for optimal consistency.
Q4: What types of dispersion aids or surface treatments are typically used with BASF K8730 to improve compatibility in polymer systems?
A: BASF K8730 is commonly processed with polymeric dispersants, low-molecular-weight waxes, or functionalized carrier resins to enhance wetting, reduce agglomeration, and improve distribution in thermoplastics and engineering resins. The optimal dispersion strategy depends on the base polymer polarity, melt viscosity, and target optical properties—formulation trials are advised.
