Q1: What is the primary chemical composition of Cathay FLOWTINT Black FF9330?
A: Cathay FLOWTINT Black FF9330 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 under major global regulatory frameworks for industrial pigments.
Q2: Is this pigment suitable for use in polyolefin compounds processed at high temperatures?
A: Yes — FF9330 is specifically formulated to withstand processing temperatures up to 300°C, making it well-suited for extrusion and injection molding of polypropylene, polyethylene, and other thermoplastics without significant color shift or degradation.
Q3: How does FF9330 compare to carbon black in terms of UV stability and dispersion behavior?
A: Unlike carbon black, FF9330 offers superior UV inertness and does not promote polymer photo-oxidation. It also demonstrates excellent dispersibility in both molten polymer matrices and aqueous systems, with reduced tendency for agglomeration during high-shear compounding.
Q4: Can FF9330 be used in food-contact compliant masterbatches?
A: FF9330 is designed for industrial and technical applications where regulatory compliance is determined by the final formulation. While the pigment itself contains no intentionally added substances restricted under major food-contact regulations, end-use compliance must be verified by the compounder through full system testing and documentation.
Q5: What is the typical dosage range for achieving deep black shades in engineering plastics?
A: Dosage depends on the base polymer, required opacity, and processing conditions, but FF9330 is generally effective at low concentrations — typically ranging from 0.1% to 2% by weight — due to its high tinting strength and excellent light absorption properties.
