Q1: What is the primary chemical composition of CATHAYGRAN Black F9330GS?
A: CATHAYGRAN Black F9330GS is a high-performance inorganic black pigment based on mixed metal oxides, formulated to deliver excellent thermal stability and UV resistance. Its exact composition is proprietary, but it contains no heavy metals regulated under RoHS or REACH Annex XIV.
Q2: Is this pigment suitable for high-temperature polymer processing, such as polypropylene or engineering plastics?
A: Yes — F9330GS is specifically engineered for demanding thermoplastic applications. It demonstrates excellent dispersion stability and color consistency during melt processing at temperatures up to 300°C, with minimal thermal degradation or gas evolution.
Q3: How does F9330GS compare to carbon black in terms of tinting strength and weatherfastness?
A: While carbon black offers higher blackness intensity, F9330GS provides superior UV stability and resistance to blooming or migration in outdoor applications. It delivers consistent jet-black shades with reduced risk of surface dusting or fading under prolonged UV exposure.
Q4: What is the recommended dosage range for optimal performance in masterbatch formulations?
A: Dosage depends on the target opacity, blackness level, and base polymer. F9330GS is typically used at low concentrations — generally ranging from 0.1% to 2% by weight — and achieves efficient dispersion with standard compounding equipment and appropriate carrier resins.
