Q1: What is the primary function of Colanyl Oxide Black IR 500 VP 5148 in polymer systems?
A: It is a high-performance black color paste based on iron oxide pigments, specifically engineered for infrared (IR) absorption and thermal stability in demanding polymer applications such as automotive interior components and technical plastics.
Q2: Which polymer matrices is this color paste compatible with?
A: Colanyl Oxide Black IR 500 VP 5148 demonstrates excellent compatibility with engineering thermoplastics including polypropylene (PP), polyethylene (PE), polyamide (PA), and thermoplastic elastomers (TPEs), particularly where consistent dispersion and heat resistance are required.
Q3: How should this paste be incorporated into a compound or masterbatch formulation?
A: It is designed for direct addition during compounding—typically introduced via side-stuffer feeder or liquid dosing system—and achieves optimal dispersion under standard melt-processing conditions without requiring pre-drying or special handling.
Q4: Does this product offer UV stability and weather resistance?
A: Yes—the iron oxide pigment system provides inherent UV stability and long-term color retention, making it suitable for both indoor and outdoor applications where resistance to fading and chalking is critical.
Q5: What is the typical dosage range for achieving full opacity and consistent black tone?
A: Dosage depends on the base polymer, desired opacity, and processing method, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight—to achieve deep, uniform black shades with minimal impact on mechanical properties.
