Q1: What is the primary chemical composition of Cathay CATHAYPURE Red R2160?
A: Cathay CATHAYPURE Red R2160 is a high-performance inorganic pigment based on iron oxide, engineered for excellent thermal stability and consistent chromatic performance in demanding processing conditions.
Q2: Is this pigment suitable for use in food-contact plastics?
A: Yes — Cathay CATHAYPURE Red R2160 is manufactured under strict quality control to meet global regulatory expectations for pigments used in food-contact applications, subject to final formulation compliance and end-use approval by relevant authorities.
Q3: How does R2160 perform under high-temperature processing, such as injection molding or extrusion?
A: This pigment exhibits outstanding thermal stability and retains its red hue with minimal color shift up to 300 °C, making it well-suited for engineering thermoplastics and high-heat polymer processing.
Q4: Can R2160 be used in both polyolefins and engineering resins?
A: Yes — R2160 demonstrates broad compatibility across polyolefins (PP, PE), PVC, PS, ABS, and many engineering resins, with good dispersion characteristics and minimal impact on mechanical properties when properly incorporated.
Q5: What is the typical dosage range for optimal coloration in plastic applications?
A: Dosage depends on the base polymer, desired shade intensity, and processing method; however, it is generally used at low concentrations, typically ranging from 0.1% to 2% by weight, with most applications falling within the lower half of that range.
