Q1: What is the primary application field for Hostatint Black GR 31 VP 5342?
A: This pigment paste is specifically developed for coloration of polyolefin-based compounds, particularly in injection molding and extrusion applications where high thermal stability, excellent dispersion, and consistent jetness are required.
Q2: Is this product suitable for food-contact plastics?
A: Hostatint Black GR 31 VP 5342 is formulated with pigments and additives compliant with major global food-contact regulations for polyolefins, subject to final formulation validation and regulatory review by the compounder or end-user.
Q3: How should this color paste be incorporated into polyolefin resins?
A: It is typically added via gravimetric or volumetric dosing directly into the feed throat or melt stream during compounding. Good mechanical mixing ensures uniform dispersion; pre-blending with carrier resin may be beneficial for very low dosage levels.
Q4: Does this paste contain heavy metals or halogenated components?
A: No — Hostatint Black GR 31 VP 5342 is formulated without intentionally added heavy metals (e.g., lead, cadmium, mercury, hexavalent chromium) and is free from halogenated solvents or carriers, supporting compliance with RoHS and similar environmental directives.
Q5: What is the recommended dosage range for achieving deep black shades in PP or HDPE?
A: Dosage depends on the base resin, processing conditions, and desired opacity/jetness, but typical usage generally ranges from 0.1% to 2% by weight — starting at lower concentrations and adjusting based on trial results is advised.
