Q1: What is the primary chemical composition of Cathay FERROTINT Black F9550L?
A: Cathay FERROTINT Black F9550L is a high-performance inorganic black pigment based on a complex iron oxide–manganese oxide spinel structure, engineered for exceptional thermal stability and chemical inertness.
Q2: Is this pigment suitable for use in heat-sensitive polymer systems such as polyolefins or engineering thermoplastics?
A: Yes — F9550L exhibits excellent thermal stability, making it well-suited for high-temperature processing conditions typical of polypropylene, polyethylene, and engineering resins like PBT and nylon, without significant color shift or decomposition.
Q3: How does F9550L compare to carbon black in terms of UV resistance and dispersion behavior?
A: Unlike carbon black, F9550L offers superior UV stability with no risk of photochemical degradation or surface blooming. Its inorganic nature provides consistent dispersion in polar and non-polar media when properly compounded, though optimal dispersion typically requires standard melt-mixing or pre-dispersion techniques.
Q4: Can F9550L be used in food-contact or regulated packaging applications?
A: F9550L is formulated to meet general requirements for pigments intended for indirect food-contact applications, including compliance with global regulatory expectations for heavy metal content and extractables. Final suitability must be confirmed per specific end-use regulations and formulation testing.
Q5: What is the typical dosage range for achieving full opacity and jetness in plastic masterbatches?
A: Dosage depends on the polymer matrix, desired shade depth, and processing method, but F9550L is generally effective at low concentrations — typically ranging from 0.1% to 2% by weight in final compounds — to deliver strong blackness and excellent hiding power.
