Q1: What is the primary chemical composition of Cathay CATHAYPURE Yellow Y2220?
A: Cathay CATHAYPURE Yellow Y2220 is a high-performance inorganic yellow pigment based on modified iron oxide and complex metal oxides, engineered for enhanced thermal stability and lightfastness without organic chromophores.
Q2: Is this pigment suitable for food-contact plastics and coatings?
A: Yes — Y2220 is formulated to meet general requirements for pigments used in food-contact applications, including compliance with major global regulatory frameworks for non-toxicity and extractable metal limits. Final regulatory acceptance depends on the complete formulation and end-use conditions.
Q3: How does Y2220 perform under high-temperature processing conditions?
A: This pigment exhibits excellent thermal stability, maintaining consistent color and dispersion integrity during standard polymer processing such as injection molding, extrusion, and calendering up to 280°C, with minimal risk of charring or hue shift.
Q4: What is the typical dosage range for optimal coloration in polyolefin applications?
A: Dosage depends on the desired shade intensity and base resin opacity, but Y2220 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight — due to its high tinting strength and efficient dispersion characteristics.
