Q1: What types of polymers is Colanyl Black N 131 compatible with?
A: Colanyl Black N 131 is specifically formulated for use in thermoplastic polymers including polyolefins (PP, PE), PS, ABS, and engineering plastics such as PA and PC. It demonstrates good dispersion stability and thermal resistance during standard melt processing conditions.
Q2: How should Colanyl Black N 131 be incorporated into a polymer formulation?
A: The paste is typically added directly to the base polymer via gravimetric or volumetric dosing systems prior to extrusion or injection molding. Pre-blending with carrier resin or using masterbatch dilution is recommended for optimal homogeneity, especially at low dosage levels.
Q3: Does Colanyl Black N 131 contain heavy metals or halogenated compounds?
A: No — Colanyl Black N 131 is formulated without intentionally added heavy metals (e.g., lead, cadmium, mercury, hexavalent chromium) and does not contain halogenated carriers or solvents, supporting compliance with common restricted substance lists for consumer and industrial applications.
Q4: What is the typical dosage range for achieving full black opacity?
A: Full black opacity is generally achieved at concentrations ranging from 0.1% to 2% by weight, depending on polymer type, part thickness, and required jetness. Lower dosages are often sufficient in thin-walled parts or when high-carbon-black loading is desired for UV protection.
