Q1: What is the primary application of Viscofil Black VBC-DE Color Paste?
A: Viscofil Black VBC-DE is a high-performance, solvent-free black color paste specifically developed for coloring polyolefin compounds—especially in injection molding and extrusion applications where excellent dispersion, thermal stability, and low plate-out are required.
Q2: Is this product suitable for food-contact or pharmaceutical packaging applications?
A: Viscofil Black VBC-DE is formulated with pigments and carriers compliant with major global food-contact regulations for polyolefins. However, final regulatory compliance depends on the complete formulation, processing conditions, and end-use requirements—users must conduct their own verification and obtain appropriate regulatory documentation from Clariant prior to use.
Q3: How should Viscofil Black VBC-DE be incorporated into polyolefin compounds?
A: It is typically introduced via masterbatch dilution or direct addition during compounding. Due to its optimized rheology and carrier compatibility, it achieves rapid wetting and uniform dispersion in molten polypropylene and polyethylene—especially at standard extrusion or twin-screw compounding temperatures.
Q4: Does this color paste contain heavy metals or halogens?
A: Viscofil Black VBC-DE is manufactured without intentionally added heavy metals (e.g., lead, cadmium, mercury, hexavalent chromium) or halogenated carriers. It aligns with Clariant’s commitment to sustainable, high-purity color solutions for demanding industrial applications.
