Q1: What is the primary chemical composition of Ferro 10399?
A: Ferro 10399 is a high-performance inorganic pigment based on a complex metal oxide system, engineered for thermal and chemical stability. Its exact formulation is proprietary, but it does not contain regulated heavy metals such as lead, cadmium, or hexavalent chromium.
Q2: Is Ferro 10399 suitable for use in food-contact plastics?
A: Yes, Ferro 10399 is designed to meet global regulatory expectations for pigments used in food-contact applications, including compliance with FDA 21 CFR §178.3297 and relevant EU framework requirements for inorganic colorants. Final regulatory acceptance depends on the full formulation and intended end-use conditions.
Q3: How does Ferro 10399 perform under high-temperature processing?
A: This pigment exhibits excellent thermal stability and retains its color integrity during standard polymer processing operations—including injection molding, extrusion, and blow molding—at temperatures up to 300°C. It shows minimal color shift or degradation even under extended residence times typical in compounding.
Q4: What types of polymers is Ferro 10399 commonly used with?
A: Ferro 10399 demonstrates broad compatibility with engineering thermoplastics such as polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), and polycarbonate (PC). It is also successfully incorporated into thermoset systems and masterbatch formulations.
