Q1: What is the primary chemical composition of Cathay FLOWTINT Black FF9550L?
A: Cathay FLOWTINT Black FF9550L is an iron oxide-based inorganic black pigment, formulated with a controlled crystalline structure to deliver consistent jetness and high thermal stability. It does not contain heavy metals such as lead, cadmium, or chromium(VI).
Q2: Is this pigment suitable for use in polyolefin compounds like PP and PE?
A: Yes — FF9550L is specifically engineered for excellent dispersion and thermal stability in polyolefin systems, including injection-molded and extruded applications. Its surface treatment supports robust melt processing up to 300°C without significant color shift or degradation.
Q3: How does FF9550L compare to carbon black in terms of UV resistance and weatherability?
A: As an inorganic oxide pigment, FF9550L offers inherently superior UV resistance and long-term weatherability compared to organic blacks or standard carbon blacks. It shows minimal fading or chalking under prolonged outdoor exposure and does not promote polymer photodegradation.
Q4: Can FF9550L be used in food-contact plastics?
A: FF9550L is manufactured under strict quality controls and complies with general requirements for inorganic pigments in food-contact polymers where permitted by local regulatory frameworks. Final compliance depends on the full formulation, processing conditions, and applicable national regulations — users must conduct their own due diligence and validation.
Q5: What is the typical dosage range for achieving deep black shades in engineering thermoplastics?
A: Dosage varies depending on the base resin, desired opacity, and processing method, but FF9550L is generally effective at low concentrations — typically ranging from 0.1% to 2% by weight — due to its high tinting strength and efficient light absorption characteristics.
