Q1: What is the primary chemical composition and classification of Sicopal K1011?
A: Sicopal K1011 is a high-performance inorganic pigment based on mixed metal oxides, classified as a complex inorganic colored pigment (CICP). It is engineered for exceptional thermal stability and chemical inertness, with no organic chromophores or volatile components.
Q2: Is Sicopal K1011 suitable for use in food-contact plastics?
A: Yes — Sicopal K1011 is specifically designed and qualified for use in food-contact applications where regulatory compliance and migration resistance are critical. Its inorganic nature ensures low extractability and long-term stability under typical processing and end-use conditions.
Q3: How does Sicopal K1011 perform under high-temperature processing conditions?
A: Sicopal K1011 exhibits excellent thermal stability, maintaining color integrity and dispersion quality during standard polymer processing methods including injection molding, extrusion, and blow molding — even at temperatures exceeding 280 °C.
Q4: What types of polymers is Sicopal K1011 typically compatible with?
A: Sicopal K1011 demonstrates broad compatibility with engineering thermoplastics such as polypropylene (PP), polyethylene (PE), polyamide (PA), and polybutylene terephthalate (PBT), as well as high-heat resins like polyphenylene sulfide (PPS) and polyetherimide (PEI).
Q5: What is the recommended dosage range for optimal coloration and performance?
A: Dosage depends on the desired shade intensity and base polymer, but Sicopal K1011 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight — due to its high tinting strength and efficient dispersion characteristics.
