Q1: What is the primary chemical composition of Ferro SPP-1011?
A: Ferro SPP-1011 is a high-performance inorganic pigment based on a complex metal oxide system, engineered for thermal and chemical stability. Its exact proprietary formulation is protected, but it contains no heavy metals regulated under RoHS or REACH Annex XIV, and is fully compliant with global food-contact-compatible pigment guidelines where applicable.
Q2: Is SPP-1011 suitable for use in polyolefin compounds exposed to high processing temperatures?
A: Yes — SPP-1011 is specifically designed for demanding thermoplastic applications, including polypropylene and polyethylene. It demonstrates excellent thermal stability up to 300 °C, minimal color shift during extrusion, and strong resistance to blooming or plate-out under typical compounding conditions.
Q3: How does SPP-1011 perform in UV-exposed outdoor applications?
A: SPP-1011 offers inherently high UV stability due to its inorganic crystalline structure. When properly compounded and dispersed, it maintains consistent color strength and hue retention in long-term outdoor exposure, making it well-suited for automotive exterior trims, construction profiles, and agricultural films.
Q4: What is the recommended dispersion method for optimal color development?
A: For best results, SPP-1011 should be incorporated using high-shear compounding — such as twin-screw extrusion or high-intensity batch mixing. Pre-dispersed masterbatches are also widely used. Adequate dispersion is critical to achieving full color strength, uniformity, and avoiding agglomerate-related defects.
Q5: Can SPP-1011 be used in food-contact plastics?
A: SPP-1011 is formulated to meet the general safety expectations for pigments in food-contact plastics under major regulatory frameworks, including FDA 21 CFR §178.3297 and EU Plastics Regulation requirements for non-primary aromatic amines and extractables. Final compliance depends on full formulation review and end-use conditions, and users should consult Ferro’s regulatory documentation for specific migration guidance.
