Q1: What is the primary application field for Viscofil Yellow A2GN?
A: Viscofil Yellow A2GN is specifically developed for coloring polyolefin-based masterbatches and compounds, with strong suitability for injection molding, blow molding, and extrusion applications where high thermal stability and dispersion performance are required.
Q2: Is this color paste compatible with food-contact polyolefin materials?
A: Viscofil Yellow A2GN is formulated without heavy metals and complies with general regulatory expectations for food-contact plastics, subject to final formulation validation. Users must confirm compliance with applicable regional regulations through full system testing and supplier documentation review.
Q3: How should Viscofil Yellow A2GN be incorporated into a polymer system?
A: It is typically introduced via twin-screw extrusion or high-intensity mixing during masterbatch production. Good dispersion is achieved under standard compounding conditions for polyolefins; pre-drying is not required, but storage in sealed containers under cool, dry conditions is recommended.
Q4: What level of thermal stability does this yellow paste offer?
A: Viscofil Yellow A2GN demonstrates robust thermal stability suitable for processing temperatures commonly encountered in polyolefin compounding and conversion—typically up to 260 °C for short residence times—without significant hue shift or degradation.
Q5: What is the typical dosage range when using this paste in polyolefin masterbatches?
A: Dosage depends on the desired shade intensity and base polymer characteristics, but it is generally used at low concentrations—commonly ranging from 0.1% to 2% by weight in the final masterbatch formulation.
