Q1: What types of polymers is Colanyl Black N 500 compatible with?
A: Colanyl Black N 500 is formulated for compatibility with a broad range of thermoplastics, including polyolefins (PP, PE), styrenics (PS, ABS), and engineering resins such as PA and PC. It is not recommended for highly polar or reactive systems like POM or certain fluoropolymers without prior testing.
Q2: How should this color paste be incorporated into polymer processing?
A: The paste is typically introduced via gravimetric or volumetric dosing systems directly into the extruder feed throat or injection molding hopper. Pre-blending with carrier resin is optional but may improve dispersion uniformity in high-speed or high-viscosity processes.
Q3: Does Colanyl Black N 500 contain heavy metals or halogens?
A: This product is manufactured without intentionally added heavy metals (e.g., lead, cadmium, mercury, hexavalent chromium) or halogenated compounds. It complies with Clariant’s internal Restricted Substances List and is suitable for applications requiring halogen-free status, subject to final formulation verification.
Q4: What is the typical dosage range for achieving full black opacity?
A: Dosage depends on polymer type, part thickness, and desired opacity, but full black coverage is generally achieved at concentrations ranging from 0.1% to 2% by weight. Lower loadings are often sufficient in thin-walled parts or when high-purity carbon black dispersion is required.
