Q1: What is the primary application of Flexonyl White RS Color Paste?
A: Flexonyl White RS Color Paste is specifically developed for coloring polyolefin-based packaging materials, including films, containers, and closures, where high whiteness, thermal stability, and low extractables are required.
Q2: Is Flexonyl White RS suitable for food-contact applications?
A: Yes — Flexonyl White RS is formulated with components compliant with major global food-contact regulations for polyolefins. It is intended for use in food packaging where regulatory compliance is verified per final application and processing conditions.
Q3: How should Flexonyl White RS be incorporated into polyolefin compounds?
A: The paste is typically added directly to the polymer melt during extrusion or injection molding. It disperses readily due to its optimized rheology and compatibility with polypropylene and polyethylene matrices, generally requiring no pre-dilution.
Q4: Does Flexonyl White RS offer improved thermal stability compared to standard titanium dioxide masterbatches?
A: Yes — Flexonyl White RS is engineered to minimize yellowing and degradation during high-temperature processing (e.g., >220 °C), delivering consistent whiteness and reduced volatile formation in demanding polyolefin applications.
Q5: What is the typical dosage range for achieving optimal whiteness and opacity?
A: Dosage depends on the base resin, desired opacity level, and processing method, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight — with efficient coverage even at the lower end of this range.
