Q1: What are the key advantages of CATHAYGRAN Black F9550GS compared to organic black pigments?
A: CATHAYGRAN Black F9550GS offers superior thermal stability, UV resistance, and chemical inertness due to its inorganic composition—making it especially suitable for high-temperature processing (e.g., engineering plastics compounding) and outdoor applications where long-term color retention is critical.
Q2: Is this pigment suitable for use in polyolefin-based masterbatches?
A: Yes, CATHAYGRAN Black F9550GS demonstrates excellent dispersibility and compatibility in polyolefin systems such as PP and PE, and maintains stable color performance during melt processing without significant degradation or blooming.
Q3: How does this pigment perform under acidic or alkaline conditions?
A: As a chemically stable inorganic pigment, CATHAYGRAN Black F9550GS exhibits high resistance to both acidic and alkaline environments, supporting reliable performance in coatings, construction materials, and industrial compounds exposed to variable pH conditions.
Q4: What is the typical dosage range when incorporating this pigment into thermoplastic formulations?
A: Dosage depends on the desired opacity and shade intensity, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight—due to its high tinting strength and efficient dispersion characteristics.
