Q1: What is the primary application area for Sanodye Red GLW pigment?
A: Sanodye Red GLW is a high-performance, solvent-stable azo pigment specifically developed for coloring polyolefin-based packaging films and injection-molded containers—particularly where excellent heat stability, low extractability, and consistent shade reproducibility are required.
Q2: Is Sanodye Red GLW suitable for food-contact applications?
A: Yes—Sanodye Red GLW is formulated to meet global regulatory expectations for indirect food contact in polyolefins, including compliance with FDA 21 CFR §178.3297 and EU Framework Regulation (EC) No 1935/2004. Final compliance depends on full formulation, processing conditions, and end-use migration testing.
Q3: How does Sanodye Red GLW perform during high-temperature processing?
A: It exhibits excellent thermal stability up to typical polyolefin processing temperatures (e.g., extrusion and injection molding at 200–260 °C), with minimal color shift or degradation—making it well-suited for demanding melt-processing operations.
Q4: What is the recommended dosage range for optimal performance?
A: Dosage depends on the desired shade intensity and polymer matrix, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in polypropylene or polyethylene—while maintaining excellent dispersion and color strength.
