Q1: What is the primary chemical composition of CATHAYPURE Black B2310?
A: CATHAYPURE Black B2310 is a high-performance inorganic black pigment based on a complex metal oxide system, engineered for thermal and chemical stability. It does not contain elemental carbon or organic dyes, distinguishing it from carbon blacks and organic pigments.
Q2: Is this pigment suitable for use in food-contact plastics?
A: Yes — CATHAYPURE Black B2310 is formulated to meet global regulatory expectations for pigments used in food-contact polymers, including compliance with general provisions for inorganic colorants under major food safety frameworks. Final regulatory acceptance depends on the complete formulation and intended application conditions.
Q3: How does B2310 perform under high-temperature processing, such as injection molding or extrusion?
A: This pigment exhibits excellent thermal stability and retains its color strength and dispersion integrity at temperatures commonly encountered in polymer processing, including polyolefin and engineering resin applications. It shows minimal color shift or degradation up to typical melt processing ranges.
Q4: What are the recommended dispersion methods for optimal performance in polymer systems?
A: For best results, pre-dispersion via high-shear compounding or masterbatch production is recommended. The pigment responds well to standard melt-mixing equipment and achieves uniform distribution without requiring specialized surfactants or coupling agents in most thermoplastic systems.
