Q1: What is the primary chemical composition of CATHAYPURE Black B1134?
A: CATHAYPURE Black B1134 is a high-performance inorganic black pigment based on a complex metal oxide system, engineered for thermal and chemical stability. Its exact composition is proprietary, but it contains no heavy metals of concern such as lead, cadmium, or mercury, and complies with global regulatory expectations for restricted substances in industrial pigments.
Q2: Is this pigment suitable for high-temperature processing applications?
A: Yes — B1134 exhibits excellent thermal stability and is routinely used in applications involving extrusion, calendering, and injection molding at temperatures up to 300 °C. It maintains color integrity and dispersion performance without significant degradation or gas evolution under typical polymer processing conditions.
Q3: How does B1134 compare to carbon black in terms of UV resistance and weatherability?
A: Unlike organic blacks or standard carbon black, B1134 offers superior UV resistance and long-term outdoor stability due to its fully inorganic nature. It shows minimal fading or chalking when exposed to sunlight and atmospheric conditions, making it preferred for demanding exterior applications where durability is critical.
Q4: Can B1134 be used in food-contact or pharmaceutical packaging materials?
A: While B1134 is not certified for direct food contact under specific food-grade regulations, it is widely employed in non-intent-to-contact layers of multilayer packaging (e.g., outer barrier or decorative layers) where migration risk is negligible. Formulators should conduct final compliance testing per applicable regional requirements.
