Q1: What is the primary chemical class of Novoperm Carmine HF3C?
A: Novoperm Carmine HF3C is a high-performance perylene-based organic pigment, belonging to the perylene diimide family. Its molecular structure delivers exceptional lightfastness, thermal stability, and resistance to migration in demanding polymer applications.
Q2: Is this pigment suitable for food-contact plastics?
A: Novoperm Carmine HF3C is not pre-approved for direct food-contact applications under major global regulatory frameworks. Its use in food-contact materials requires full formulation-level compliance assessment by the end-user, including evaluation of extractables, migration potential, and adherence to applicable regional regulations.
Q3: Which polymers show optimal dispersion and color development with this pigment?
A: Novoperm Carmine HF3C demonstrates excellent compatibility and dispersion in engineering thermoplastics such as polypropylene (PP), polyethylene (PE), and polycarbonate (PC), particularly when processed via injection molding or extrusion. Performance in polar resins like PET may require optimized dispersing aids or masterbatch formulation.
Q4: How does HF3C differ from other Novoperm Carmine grades?
A: The 'HF3C' designation indicates a specific particle size distribution and surface treatment engineered for enhanced heat stability and reduced agglomeration during high-temperature processing—especially beneficial in thin-wall PP applications and automotive interior components where long-term color retention is critical.
Q5: What are typical dosage levels in polymer coloration?
A: Dosage depends on the target shade strength and polymer matrix, but Novoperm Carmine HF3C is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in final compounds—due to its high tinting strength and efficient chromophore utilization.
