Q1: What is the primary application field for Hostatint Black GR 500?
A: Hostatint Black GR 500 is specifically developed for coloring polyolefin-based packaging materials, including flexible films, blow-molded containers, and injection-molded closures—particularly where high jetness, thermal stability during processing, and low extractables are required.
Q2: Is this color paste suitable for food-contact applications?
A: Yes, Hostatint Black GR 500 is formulated to meet regulatory expectations for indirect food contact in polyolefins, subject to final compliance verification within the full formulation and processing conditions. It contains no intentionally added heavy metals or restricted aromatic amines.
Q3: How should Hostatint Black GR 500 be incorporated into polyolefin compounds?
A: It is typically introduced via masterbatch dilution or direct addition during compounding. Good dispersion is achieved using standard melt-processing equipment; pre-drying is not required, but storage under dry, cool conditions is recommended to maintain consistency.
Q4: Does this product offer resistance to migration during storage or end-use?
A: Yes, Hostatint Black GR 500 exhibits low tendency for pigment migration due to its optimized polymer-compatible carrier system and strong pigment-polymer affinity in polyolefin matrices, especially after proper dispersion and thermal history control.
