Q1: What is the primary application field for Hostatint Red FGR 531?
A: Hostatint Red FGR 531 is specifically developed for coloring polyolefin-based packaging materials, including flexible films and rigid containers used in food, pharmaceutical, and consumer goods applications. It is optimized for high-temperature processing such as extrusion and injection molding.
Q2: Is this color paste suitable for food-contact applications?
A: Yes — Hostatint Red FGR 531 is formulated to comply with global regulatory expectations for indirect food contact, including FDA 21 CFR and relevant EU frameworks. Final compliance depends on the full formulation, processing conditions, and end-use requirements, so validation testing is recommended for each specific application.
Q3: How should this paste be incorporated into polyolefin compounds?
A: The paste is designed for direct addition during compounding — typically via side-stuffer feeder or gravimetric dosing systems. It exhibits excellent dispersion stability and melt compatibility with PP and PE matrices, minimizing agglomeration and streaking under standard processing conditions.
Q4: What are the key handling and storage recommendations?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from direct sunlight and moisture. Avoid freezing. For optimal performance, use within 12 months of receipt. Prior to use, gently stir to ensure homogeneity if sedimentation has occurred during storage.
