Q1: What types of polymer systems is Colanyl Yellow 5GX 130 Color Paste compatible with?
A: This color paste is specifically formulated for use in polyolefins such as PP and HDPE, and demonstrates good compatibility in thermoplastic elastomers and certain engineering plastics. Performance in polar polymers like PET or PA should be verified through application testing.
Q2: How should Colanyl Yellow 5GX 130 be incorporated into the polymer melt?
A: It is typically introduced via side-feeding or gravimetric dosing directly into the extruder throat or injection molding machine hopper. Pre-blending with base resin at low shear is also effective to ensure uniform dispersion prior to processing.
Q3: Does this color paste offer thermal stability suitable for high-temperature processing?
A: Yes — Colanyl Yellow 5GX 130 is engineered for robust thermal stability during standard polyolefin processing conditions, including extrusion and injection molding up to typical melt temperatures. Discoloration or degradation is minimized under recommended residence times and temperature profiles.
Q4: What is the typical dosage range for achieving target shade intensity?
A: Dosage depends on formulation requirements and desired opacity or chroma, but it is generally used at low concentrations — typically ranging from 0.1% to 2% by weight relative to the base polymer. Optimal loading should be determined through lab-scale trials to balance color strength, dispersion quality, and cost efficiency.
