Q1: What is the primary application area for Hostatint Orange GR 30 Color Paste?
A: Hostatint Orange GR 30 is specifically developed for coloring polyolefin-based packaging materials, including flexible films and rigid containers used in food, personal care, and household product applications. Its formulation prioritizes dispersion stability, heat stability during extrusion or injection molding, and compatibility with common PP and PE resins.
Q2: Is this color paste suitable for food-contact applications?
A: Yes — Hostatint Orange GR 30 is manufactured under Clariant’s stringent quality and regulatory compliance program for food-contact plastics. It is designed to meet general requirements for indirect food contact as outlined in major global frameworks, and full regulatory documentation (including declarations of compliance) is available upon request for specific end-use conditions.
Q3: How should this paste be incorporated into polyolefin compounds?
A: Hostatint Orange GR 30 is typically introduced via masterbatch dilution or direct high-shear compounding. For optimal dispersion, it is recommended to pre-mix with the base polymer at low shear before final melt processing. Dosage depends on formulation requirements but generally ranges from 0.1% to 2% by weight, depending on desired shade intensity and substrate thickness.
Q4: Does this product contain heavy metals or halogenated components?
A: No — Hostatint Orange GR 30 is formulated without intentionally added heavy metals (e.g., lead, cadmium, mercury, hexavalent chromium) and is free from halogenated solvents or carriers. It complies with Clariant’s internal EcoTain® sustainability criteria and supports compliance with RoHS and similar restricted-substance initiatives.
