Q1: What is the primary application of Hostatint White A-R 100?
A: Hostatint White A-R 100 is a high-performance white color paste specifically developed for coloring polyolefin-based packaging materials, including blow-molded and injection-molded containers used in food, personal care, and household product applications.
Q2: Is this color paste suitable for food-contact applications?
A: Yes — Hostatint White A-R 100 is formulated with FDA-compliant and EU-regulated pigments and additives appropriate for indirect food-contact packaging. Final compliance depends on full formulation, processing conditions, and end-use requirements, and users should validate suitability per applicable regional regulations.
Q3: How is Hostatint White A-R 100 typically incorporated into polyolefin resins?
A: It is designed for direct addition during compounding or masterbatch production, and can also be used in inline dosing systems. Due to its optimized rheology and dispersion stability, it integrates efficiently into molten polypropylene and polyethylene streams without requiring pre-dilution.
Q4: Does this paste offer resistance to thermal degradation during processing?
A: Yes — Hostatint White A-R 100 is engineered for excellent thermal stability in standard polyolefin processing temperatures (up to approximately 260 °C), helping maintain consistent whiteness and minimize yellowing or haze development during extrusion or molding.
Q5: What is the typical dosage range when using this color paste?
A: Dosage depends on the desired opacity, base resin, and processing method, but it is generally used at low concentrations — typically ranging from 0.1% to 2% by weight relative to the polymer matrix.
