Q1: What is the primary application area for Hostatint Yellow 2GXD 531 Color Paste?
A: This pigment paste is specifically developed for coloring polyolefin-based packaging materials, including flexible films and rigid containers, where high thermal stability and good dispersion performance are required during extrusion and thermoforming processes.
Q2: Is Hostatint Yellow 2GXD 531 suitable for food-contact applications?
A: Yes — it is formulated to meet global regulatory expectations for indirect food contact in polyolefins, subject to compliance with applicable regional requirements and final formulation validation by the end user.
Q3: How should this color paste be incorporated into polyolefin compounds?
A: It is typically added directly during compounding via side-feeding or gravimetric dosing systems. Good dispersion is achieved under standard melt processing conditions; pre-mixing with carrier resin is not required but may be considered for highly sensitive formulations.
Q4: What is the typical dosage range for achieving target shade intensity?
A: Dosage depends on the base polymer, desired opacity, and processing method, but generally ranges from 0.1% to 2% by weight — with most standard packaging applications falling between 0.3% and 1.0%.
