Q1: What is the primary chemical composition of Cathay CATHAYPURE Yellow Y2230?
A: Cathay CATHAYPURE Yellow Y2230 is a high-performance inorganic yellow pigment based on a modified complex metal oxide system, engineered for enhanced thermal stability and chromatic purity. It does not contain lead, cadmium, or chromium(VI), aligning with modern regulatory expectations for heavy-metal-reduced pigments.
Q2: Is this pigment suitable for high-temperature polymer processing applications?
A: Yes — Y2230 is specifically formulated for excellent thermal stability and is routinely used in engineering thermoplastics such as polyamide, polypropylene, and polyester processed at temperatures up to 280°C. Its inorganic nature ensures minimal color shift or degradation under typical melt-processing conditions.
Q3: How does Y2230 compare to organic yellow pigments in terms of lightfastness and weather resistance?
A: As an inorganic pigment, Y2230 offers significantly superior lightfastness, UV resistance, and long-term outdoor durability compared to most organic yellows. It maintains color integrity under prolonged exposure to sunlight and atmospheric conditions without requiring additional UV stabilizers in many standard formulations.
Q4: Can Y2230 be used in food-contact plastics?
A: While Y2230 is free from regulated heavy metals and designed for high-purity applications, its use in food-contact plastics requires evaluation against applicable regional regulations (e.g., FDA 21 CFR, EU Plastics Regulation) and must be confirmed through full formulation testing and compliance documentation by the end-user or compounder.
