Heubach HEUCODUR Black 9-100 Inorganic Pigment – Frequently Asked Questions (FAQ)

Q1: What is the primary chemical composition of HEUCODUR Black 9-100?

A: HEUCODUR Black 9-100 is a high-performance inorganic black pigment based on a mixed metal oxide system, typically incorporating cobalt, nickel, and chromium oxides in a spinel crystal structure. It is not a carbon-based or iron oxide black, offering enhanced thermal and chemical stability.

Q2: Is this pigment suitable for high-temperature polymer processing, such as polyamide or polyphenylene sulfide (PPS)?

A: Yes — HEUCODUR Black 9-100 is specifically engineered for demanding high-heat applications. It demonstrates excellent thermal stability up to at least 900 °C in air and maintains color integrity during melt processing of engineering thermoplastics, including those processed above 300 °C.

Q3: How does HEUCODUR Black 9-100 compare to standard iron oxide blacks in terms of UV resistance and weathering performance?

A: Unlike conventional iron oxide blacks, HEUCODUR Black 9-100 exhibits superior UV stability and long-term weathering resistance due to its inert, crystalline inorganic matrix. It shows negligible fading or chalking under prolonged outdoor exposure and is widely used where permanent black shade retention is critical.

Q4: Can this pigment be used in food-contact or pharmaceutical packaging applications?

A: HEUCODUR Black 9-100 is not approved for direct food-contact applications under current global regulatory frameworks. Its use is intended for industrial, automotive, construction, and durable goods applications where regulatory compliance for indirect contact or non-food scenarios applies.

Q5: What is the typical dosage range when dispersing HEUCODUR Black 9-100 in thermoplastic compounds?

A: Dosage depends on the desired opacity, shade depth, and base polymer, 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 light absorption properties.
