Q1: What is the primary application field for Colanyl Oxide Black B 532 VP 6114?
A: This pigment paste is specifically developed for coloring polyolefin compounds—especially PP and HDPE—in demanding applications such as automotive interior parts, technical injection-molded components, and industrial packaging where high thermal stability and dispersion consistency are required.
Q2: Is this product suitable for food-contact plastics?
A: Colanyl Oxide Black B 532 VP 6114 is formulated without intentionally added heavy metals or restricted aromatic amines, and it is designed to meet general requirements for food-contact compliance in polyolefins—however, final regulatory approval depends on the complete formulation, processing conditions, and applicable regional regulations. Users must conduct full migration and compliance testing for their specific application.
Q3: How should this color paste be incorporated into polyolefin compounds?
A: It is typically added via gravimetric or volumetric dosing directly into the extruder feed throat or side-stuffer during compounding. Good mixing efficiency and moderate shear conditions are recommended to ensure uniform dispersion without pigment degradation. Pre-dilution in base resin is not required but may be considered for highly sensitive processes.
Q4: Does this paste contain solvents or volatile organic compounds (VOCs)?
A: No, Colanyl Oxide Black B 532 VP 6114 is a solvent-free, VOC-free paste based on a polyolefin-compatible carrier system. It contains no added plasticizers, phthalates, or halogenated solvents, supporting low-emission processing and improved workplace safety.
Q5: What is the recommended dosage range for achieving optimal black shade intensity?
A: Dosage depends on the target opacity, substrate thickness, and desired jetness—but it is generally used at low concentrations, typically ranging from 0.1% to 2% by weight in the final compound. Optimal loading should be determined through small-scale trials to balance color strength, dispersion quality, and mechanical performance.
