Q1: What is the primary chemical composition of CATHAYPURE Yellow Y5100?
A: CATHAYPURE Yellow Y5100 is a high-performance inorganic yellow pigment based on modified iron oxide–zinc oxide composite chemistry, engineered for enhanced thermal stability and chromatic purity in demanding processing environments.
Q2: Is this pigment suitable for use in food-contact plastics?
A: Yes — CATHAYPURE Yellow Y5100 is formulated to meet general regulatory expectations for pigments in food-contact plastic applications, including compliance with major global frameworks for heavy metal limits and extractable impurities. Final regulatory acceptance depends on the complete formulation and end-use conditions.
Q3: How does Y5100 perform under high-temperature processing, such as injection molding or extrusion?
A: This pigment exhibits excellent thermal stability, retaining its color strength and hue integrity at temperatures up to 300 °C, making it well-suited for engineering thermoplastics and high-speed processing lines without significant degradation or gas evolution.
Q4: Can Y5100 be used in polyolefin masterbatches?
A: Yes — Y5100 demonstrates excellent compatibility and dispersion stability in polyolefin-based masterbatches, including PP and PE systems. It achieves uniform coloration with low dusting and minimal plate-out during compounding and downstream processing.
