Q1: What is the primary application field for Hostatint Yellow E-H7G Color Paste?
A: Hostatint Yellow E-H7G is specifically developed for coloring polyolefin-based packaging materials, including flexible films and rigid containers used in food, personal care, and household product applications.
Q2: Is this color paste suitable for food-contact applications?
A: Yes — Hostatint Yellow E-H7G is formulated with pigments and additives compliant with major global food-contact regulations for polyolefins, subject to final formulation validation and end-use conditions.
Q3: How should the paste be incorporated into polyolefin compounds?
A: It is typically added via masterbatch dilution or direct high-shear compounding. Good dispersion is achieved under standard extrusion conditions for polypropylene and polyethylene, with dosage depending on formulation requirements and desired shade intensity.
Q4: Does this product offer good thermal stability during processing?
A: Yes — Hostatint Yellow E-H7G is engineered for excellent thermal stability in polyolefin processing, maintaining consistent hue and minimal degradation up to typical melt temperatures encountered in extrusion and injection molding.
Q5: What are the recommended storage conditions?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from direct sunlight and sources of heat. Avoid freezing and prolonged exposure to high humidity to preserve rheological stability and dispersion quality.
