Q1: What is the primary application area for Hostatint Yellow E-HRD Color Paste?
A: Hostatint Yellow E-HRD is specifically developed for coloring polyolefin-based packaging materials, including flexible films and rigid containers intended for food contact applications where regulatory compliance and thermal stability are critical.
Q2: Is this color paste suitable for high-temperature processing such as injection molding or extrusion?
A: Yes — Hostatint Yellow E-HRD is engineered for excellent thermal stability and dispersion performance in polyolefin melts, making it suitable for standard polypropylene and polyethylene processing conditions, including extrusion, blow molding, and injection molding.
Q3: How should the paste be incorporated into polyolefin formulations?
A: The paste is typically added directly to the polymer melt during compounding or masterbatch production. It disperses readily under standard shear conditions and does not require pre-drying or special handling prior to use.
Q4: Does Hostatint Yellow E-HRD comply with food contact regulations?
A: This product is formulated to meet widely recognized food contact requirements for polyolefins, including general compliance with EU Framework Regulation (EC) No 1935/2004 and FDA 21 CFR §178.3297 for colorants in polymers, subject to final formulation and end-use conditions.
Q5: What is the typical dosage range when using this paste in polyolefin applications?
A: Dosage depends on the desired shade intensity and base polymer characteristics, but it is generally used at low concentrations — typically ranging from 0.1% to 2% by weight relative to the polymer matrix.
