Cathay CATHAYPURE Black B1105 Inorganic Pigment – Frequently Asked Questions (FAQ)

Q1: What is the primary chemical composition of CATHAYPURE Black B1105?

A: CATHAYPURE Black B1105 is a high-performance inorganic black pigment based on mixed metal oxides, engineered for thermal and chemical stability. Its exact composition is proprietary, but it contains no 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 — CATHAYPURE Black B1105 is formulated to meet general requirements for pigments used in food-contact polymer applications, including compliance with global regulatory expectations for heavy metals and extractables. Final regulatory suitability depends on the specific end-use application, processing conditions, and regional food contact legislation.

Q3: How does B1105 perform under high-temperature processing, such as injection molding or extrusion?

A: B1105 exhibits excellent thermal stability and retains its color integrity and dispersion characteristics at temperatures commonly encountered in polyolefin, engineering plastic, and thermoset processing — typically up to 300 °C and beyond, depending on residence time and atmosphere.

Q4: What types of polymer systems is B1105 most compatible with?

A: B1105 demonstrates broad compatibility across polyolefins (PP, PE), PVC, ABS, PS, and engineering resins such as PA and PBT. It is also widely used in masterbatch formulations due to its good dispersibility and low dusting tendency.

Q5: What is the typical dosage range when using B1105 in plastic coloration?

A: Dosage depends on the required opacity, shade depth, and base polymer, but B1105 is generally effective at low concentrations — typically ranging from 0.1% to 2% by weight in final compounds. Its high tinting strength allows for efficient usage without compromising mechanical properties.
