Cathay CATHAYGRAN Black F9340GS Inorganic Pigment – Frequently Asked Questions (FAQ)

Q1: What are the key advantages of CATHAYGRAN Black F9340GS compared to organic black pigments?

A: CATHAYGRAN Black F9340GS is an inorganic pigment offering superior thermal stability, lightfastness, and chemical resistance—making it especially suitable for high-temperature processing (e.g., engineering thermoplastics) and outdoor applications where long-term color retention is critical. Unlike many organic blacks, it does not suffer from significant blooming or migration under heat stress.

Q2: Is this pigment suitable for food-contact plastics?

A: CATHAYGRAN Black F9340GS is formulated using metal oxide-based chemistry and is intended for general industrial use. While it contains no intentionally added heavy metals beyond permitted trace levels, formal compliance with food-contact regulations (e.g., FDA 21 CFR or EU Framework Regulation) requires full formulation-level testing and validation by the end-user under their specific processing and application conditions.

Q3: How well does it disperse in polymer systems?

A: The pigment is surface-treated to enhance compatibility and dispersion in both polar and non-polar thermoplastics. It typically achieves excellent color development and uniformity with standard melt compounding equipment—though optimal dispersion may require appropriate screw design, residence time, and temperature profile depending on the base resin.

Q4: Can it be used in polyolefins such as PP and PE?

A: Yes—CATHAYGRAN Black F9340GS is widely used in polypropylene and polyethylene applications, including injection-molded parts, blow-molded containers, and fibers. Its inert nature ensures minimal impact on polymer mechanical properties, and it maintains consistent jetness and undertone across varying processing temperatures.
