Q1: What is the primary chemical composition of Ferro SPP-8008?
A: Ferro SPP-8008 is a high-performance inorganic pigment based on a complex metal oxide system, engineered for thermal and chemical stability. Its exact composition is proprietary to Ferro Corporation and optimized for consistent color development and dispersion behavior in demanding polymer and ceramic applications.
Q2: Is SPP-8008 suitable for food-contact plastics?
A: SPP-8008 is formulated to meet applicable global regulatory expectations for pigments used in food-contact polymers, including compliance with FDA 21 CFR §178.3297 and relevant EU framework requirements for inorganic colorants. Final regulatory clearance depends on the complete formulation, processing conditions, and end-use application, and users are responsible for verifying suitability with their regulatory team.
Q3: How does SPP-8008 perform under high-temperature processing conditions?
A: SPP-8008 exhibits excellent thermal stability and retains its color integrity during high-shear compounding and melt processing up to approximately 300 °C, making it well-suited for engineering thermoplastics such as polyamide, PBT, and polyphenylene sulfide.
Q4: What is the recommended method for incorporating SPP-8008 into polymer systems?
A: For optimal dispersion and color uniformity, SPP-8008 is typically introduced via masterbatch or dry-blend compounding. Pre-dispersed masterbatches are strongly recommended for high-clarity or high-gloss applications. Direct addition may require extended mixing time and higher shear to achieve full deagglomeration.
Q5: Does SPP-8008 contain heavy metals regulated under RoHS or REACH?
A: SPP-8008 is manufactured without intentionally added lead, cadmium, mercury, or hexavalent chromium, and conforms to RoHS Directive (2011/65/EU) and REACH SVHC screening criteria. It is not classified as hazardous under GHS and presents no known bioaccumulation or ecotoxicological concerns when used as directed.
