Q1: What is the primary chemical composition and classification of Sicotan K2011FG?
A: Sicotan K2011FG is a high-performance inorganic pigment based on mixed metal oxides, specifically engineered for thermal and chemical stability. It belongs to the class of complex inorganic colored pigments (CICPs), offering excellent opacity, lightfastness, and resistance to weathering without relying on heavy metals such as lead or cadmium.
Q2: Is Sicotan K2011FG suitable for use in food-contact plastics?
A: Yes, Sicotan K2011FG is designed for applications requiring regulatory compliance in food-contact materials, including polyolefins and engineering thermoplastics. Its inert, non-leaching nature and absence of restricted substances support suitability where migration performance and extractable residue limits are critical — subject to final formulation validation and applicable regional requirements.
Q3: How does Sicotan K2011FG perform under high-temperature processing conditions?
A: Sicotan K2011FG exhibits outstanding thermal stability, retaining color integrity and dispersion quality during standard polymer processing operations—including injection molding, extrusion, and blow molding—up to temperatures exceeding 300 °C. This makes it especially well-suited for demanding high-melt-index resins and engineering polymers.
Q4: What types of polymer systems show optimal compatibility with Sicotan K2011FG?
A: Sicotan K2011FG demonstrates broad compatibility across polyolefins (PP, HDPE, LDPE), polyesters (PET, PBT), and certain engineering thermoplastics. It is typically supplied in a surface-treated form to enhance dispersion and interfacial adhesion, supporting consistent color development and minimal plate-out during melt processing.
Q5: What is the recommended approach for achieving uniform dispersion in masterbatch production?
A: For optimal dispersion, Sicotan K2011FG should be incorporated using high-shear compounding techniques—such as twin-screw extrusion—with appropriate residence time and temperature profiles. Pre-blending with carrier resin prior to extrusion, along with controlled feed rate and screw design, helps ensure homogeneous distribution and minimizes agglomeration.
