Q1: What is the primary application field for Hostatint Oxide Green G 531 VP 5405?
A: This pigment paste is primarily formulated for coloring polyolefin compounds—especially PP and HDPE—in applications requiring high thermal stability, good dispersion, and resistance to blooming during processing and end-use.
Q2: Is this color paste suitable for food-contact plastics?
A: Hostatint Oxide Green G 531 VP 5405 is designed for use in food-contact compliant formulations when incorporated into approved polymer systems and processed under validated conditions; final regulatory compliance depends on the full formulation, processing parameters, and applicable regional regulations.
Q3: How should this paste be dispersed in polyolefin melts?
A: Optimal dispersion is achieved using standard compounding equipment such as twin-screw extruders; pre-mixing with a portion of the base resin prior to extrusion enhances homogeneity and minimizes agglomeration.
Q4: What is the typical dosage range for achieving medium to deep green shades?
A: Dosage varies depending on the desired shade intensity and base polymer opacity, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight relative to the total compound.
