Q1: What is the primary application advantage of Nubiperf E-19 compared to standard ultramarine pigments?
A: Nubiperf E-19 is specially engineered for enhanced thermal stability and improved dispersion in demanding polymer systems, particularly during high-temperature processing such as injection molding or extrusion. Its optimized particle surface treatment supports superior color consistency and reduced agglomeration in both polar and semi-crystalline resins.
Q2: Is Nubiperf E-19 suitable for use in food-contact plastics?
A: Yes — Nubiperf E-19 is manufactured under strict quality control protocols compliant with global food-contact regulations for colorants in plastics. It is intended for applications where regulatory approval is required, though final compliance depends on the complete formulation and end-use conditions.
Q3: How does Nubiperf E-19 perform in polypropylene (PP) and polyethylene (PE)?
A: It demonstrates excellent compatibility and color development in both homopolymer and copolymer PP, as well as in HDPE and LDPE. Its low moisture sensitivity and tailored hydrophobic surface minimize blooming and improve long-term color retention under thermal and UV exposure.
Q4: What is the recommended method for incorporating Nubiperf E-19 into masterbatches?
A: For optimal dispersion, it is recommended to use high-shear compounding techniques — such as twin-screw extrusion — with controlled temperature profiles. Pre-drying is generally not required, but storage under dry conditions is advised to maintain flowability and handling performance.
