Cathay CATHAYMAG Black MO4238 Inorganic Pigment – Frequently Asked Questions (FAQ)

Q1: What is the primary chemical composition of CATHAYMAG Black MO4238?

A: CATHAYMAG Black MO4238 is a high-performance inorganic black pigment based on a complex metal oxide system, engineered for thermal and chemical stability. Its exact composition is proprietary, but it contains no heavy metals of concern such as lead, cadmium, or hexavalent chromium, and complies with major global regulatory expectations for restricted substances.

Q2: Is this pigment suitable for use in polyolefin compounds exposed to high processing temperatures?

A: Yes — MO4238 is specifically formulated for excellent thermal stability and is widely used in polypropylene and polyethylene applications processed via extrusion, injection molding, or blow molding. It maintains consistent color strength and dispersion integrity at typical melt temperatures up to 300 °C without significant degradation or gas evolution.

Q3: How does MO4238 compare to carbon black in terms of UV resistance and weathering performance?

A: Unlike organic blacks or standard carbon black, MO4238 offers superior UV inertness and long-term outdoor stability due to its fully inorganic, crystalline structure. It shows negligible fading or chalking under accelerated weathering tests and is preferred where color retention and minimal surface degradation are critical — especially in automotive exterior parts and architectural profiles.

Q4: Can MO4238 be used in food-contact plastics?

A: While MO4238 contains no intentionally added restricted substances and exhibits low extractability, formal food-contact compliance depends on the final polymer matrix, processing conditions, and applicable regional regulations. Customers intending food-contact use must conduct full migration testing and obtain regulatory validation specific to their application and jurisdiction.
