Q1: What is the primary chemical composition of Cathay FLOWTINT Yellow FF5400?
A: Cathay FLOWTINT Yellow FF5400 is a high-performance inorganic yellow pigment based on a modified iron oxide–zinc oxide composite system, engineered for enhanced thermal stability and chromatic consistency in demanding polymer processing environments.
Q2: Is this pigment suitable for food-contact plastic applications?
A: While Cathay FLOWTINT Yellow FF5400 is formulated without heavy metals such as lead, cadmium, or mercury, its suitability for food-contact applications depends on final regulatory approval within the target jurisdiction and full compliance with the end-product’s processing conditions and migration requirements. Users must validate compliance through certified third-party testing per applicable local regulations.
Q3: How does FF5400 perform under high-temperature processing, such as injection molding or extrusion?
A: This pigment demonstrates excellent thermal stability, maintaining color integrity and dispersion quality at temperatures commonly encountered in polyolefin and engineering thermoplastic processing—typically up to 280 °C for short residence times. Its optimized particle surface treatment supports resistance to thermal degradation and minimizes color shift during melt processing.
Q4: What is the recommended method for incorporating FF5400 into polymer systems?
A: For optimal dispersion and performance, FF5400 is typically introduced via masterbatch preparation using standard compounding equipment. It is compatible with common carrier resins such as LDPE, PP, and EVA. Pre-drying is not generally required, but moisture control is advised for hygroscopic base polymers to avoid surface defects.
