Q1: What is the primary chemical class of Novoperm Bordeaux HF3R?
A: Novoperm Bordeaux HF3R is a high-performance perylene-based organic pigment, belonging to the perylene diimide family, known for exceptional lightfastness, thermal stability, and resistance to migration in demanding polymer applications.
Q2: Is this pigment suitable for food-contact plastics?
A: Novoperm Bordeaux HF3R is designed for use in non-food-contact applications. For food-contact plastics, Clariant offers alternative pigments specifically compliant with relevant regional regulatory frameworks — consult your Clariant technical representative for suitable options.
Q3: Which polymers is Novoperm Bordeaux HF3R most commonly used in?
A: This pigment demonstrates excellent compatibility and dispersion stability in engineering thermoplastics such as polyamide (PA), polybutylene terephthalate (PBT), and polyethylene terephthalate (PET), especially where high-temperature processing and long-term color retention are required.
Q4: How does HF3R differ from other Novoperm Bordeaux grades?
A: The “HF3R” designation indicates an optimized grade for high-flow, high-heat resistance applications—offering improved melt dispersibility and reduced plate-out tendency compared to standard Bordeaux variants, particularly in high-shear compounding and injection molding processes.
Q5: What is the recommended method for incorporating Novoperm Bordeaux HF3R into polymer systems?
A: Best results are achieved via masterbatch preparation using twin-screw extrusion under controlled temperature and shear conditions. Direct addition is possible but requires careful optimization of dispersion parameters to ensure uniform color development and optimal performance.
