Q1: What is the primary chemical composition of Cathay CATHAYGRAN Yellow F5700GS?
A: Cathay CATHAYGRAN Yellow F5700GS is a high-performance inorganic yellow pigment based on a stabilized iron oxide–zinc oxide composite system, engineered for thermal and chemical stability in demanding polymer processing environments.
Q2: Is this pigment suitable for food-contact plastics?
A: Yes — F5700GS is formulated to comply with global food-contact regulations for pigments used in polyolefins, polyesters, and engineering thermoplastics, subject to final formulation validation and regulatory review by the end-user.
Q3: How does F5700GS perform under high-temperature processing conditions?
A: This pigment exhibits excellent thermal stability, maintaining consistent hue and dispersion integrity during extrusion and injection molding processes up to 300 °C, making it well-suited for polypropylene, PET, and engineering resins.
Q4: What is the typical dosage range when using F5700GS in plastic masterbatches?
A: Dosage depends on the required shade strength and base polymer, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight in final compounded products.
