Q1: What is the primary chemical composition of CATHAYGRAN Black F9560GS?
A: CATHAYGRAN Black F9560GS is a high-performance inorganic black pigment based on a complex mixed-metal oxide system, engineered for thermal and chemical stability. It does not contain elemental carbon or organic dyes, distinguishing it from carbon blacks and organic pigments.
Q2: Is this pigment suitable for use in food-contact plastics?
A: Yes — CATHAYGRAN Black F9560GS is formulated to meet general requirements for pigments used in food-contact polymeric materials. It is non-leaching under typical processing and end-use conditions, and its inorganic nature supports compliance with major global food-contact frameworks when incorporated into approved resin systems.
Q3: How does F9560GS perform under high-temperature processing, such as injection molding or extrusion?
A: This pigment exhibits excellent thermal stability, retaining its color strength and integrity at temperatures commonly encountered in polymer processing — including up to 300°C for short residence times. It shows minimal degradation or gas evolution, making it well-suited for engineering thermoplastics and high-melt-index applications.
Q4: Can F9560GS be used in UV-stabilized outdoor applications?
A: Yes — as an inorganic pigment, F9560GS offers inherent UV resistance and lightfastness. When compounded into properly stabilized polymer systems, it delivers long-term color retention and minimal chalking or fading under prolonged outdoor exposure.
Q5: What is the typical dosage range for achieving full opacity and consistent blackness in polyolefins?
A: Dosage depends on formulation requirements and desired shade depth, but full opacity in polyolefins is generally achieved at low concentrations — typically ranging from 0.1% to 2% by weight. Optimal dispersion and masterbatch dilution ratios should be confirmed through application-specific trials.
