Q1: What is the primary application field for Flexonyl Yellow DGR-LA Color Paste?
A: Flexonyl Yellow DGR-LA is specifically developed for coloring polyolefin-based packaging materials, including flexible films and rigid containers intended for food contact applications, where high thermal stability and excellent dispersion are required during extrusion or injection molding.
Q2: Is this color paste compatible with common polyolefin processing methods?
A: Yes — Flexonyl Yellow DGR-LA is formulated for robust performance in standard polyolefin processes such as blown film extrusion, cast film production, and injection molding. It demonstrates good melt stability and minimal plate-out under typical processing temperatures.
Q3: How should the dosage be determined for optimal color strength and consistency?
A: Dosage depends on formulation requirements and desired shade intensity, but it is typically used at low concentrations in polyolefin masterbatches. A general starting range is 0.1% to 2% by weight relative to the base polymer, with adjustments based on dispersion efficiency and final part thickness.
Q4: Does Flexonyl Yellow DGR-LA contain heavy metals or halogens?
A: No — this product is formulated without intentionally added heavy metals (e.g., lead, cadmium, mercury, hexavalent chromium) or halogenated compounds, supporting compliance with global regulatory expectations for food-contact plastics.
