Q1: What is the primary chemical composition of Ferro SPP-3070?
A: Ferro SPP-3070 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 under Ferro’s intellectual property, but it contains no heavy metals of concern such as lead, cadmium, or mercury, and complies with global regulatory expectations for restricted substances.
Q2: Is SPP-3070 suitable for use in food-contact plastics?
A: Yes — SPP-3070 is specifically designed and tested for applications requiring compliance with food-contact regulations in major markets. It is widely used in polyolefins, PET, and engineering thermoplastics intended for food packaging and processing equipment, provided final formulations undergo appropriate migration evaluation per applicable local requirements.
Q3: How does SPP-3070 perform under high-temperature processing conditions?
A: SPP-3070 exhibits excellent thermal stability, maintaining color integrity and dispersion performance during standard polymer processing operations including injection molding, extrusion, and blow molding at temperatures up to 300 °C. It shows minimal degradation or gas evolution, supporting consistent batch-to-batch quality in demanding manufacturing environments.
Q4: What are the recommended dispersion methods for optimal performance?
A: For best results, SPP-3070 should be incorporated using high-shear compounding techniques — such as twin-screw extrusion or intensive melt mixing — to ensure uniform distribution and full deagglomeration. Pre-dispersed masterbatches are also available and often preferred for simplified handling and improved reproducibility across production scales.
Q5: Can SPP-3070 be used in outdoor applications requiring UV resistance?
A: Yes — as an inorganic pigment, SPP-3070 offers inherently high lightfastness and UV stability. It is routinely selected for exterior-grade plastics, automotive components, and construction materials where long-term color retention under sunlight exposure is critical.
