Q1: What is the primary chemical class of Novoperm Orange HL 70?
A: Novoperm Orange HL 70 is a high-performance, non-metallic organic pigment belonging to the perylene diimide derivative family, offering excellent lightfastness and thermal stability.
Q2: Is this pigment suitable for food-contact plastics?
A: Novoperm Orange HL 70 is not certified for direct food-contact applications under global regulatory frameworks. It is intended for general-purpose industrial plastics, coatings, and inks where regulatory compliance for food contact is not required.
Q3: How does HL 70 compare to standard Novoperm Orange pigments in terms of heat stability?
A: The 'HL' designation indicates enhanced heat stability—Novoperm Orange HL 70 maintains color integrity at processing temperatures up to 300 °C in polyolefins and engineering thermoplastics, making it especially suitable for demanding melt-processing applications.
Q4: What dispersion methods are recommended for optimal performance?
A: For best results, use high-shear compounding or extrusion with compatible carrier resins. Pre-dispersed concentrates are widely available and recommended to ensure uniform distribution and minimize agglomeration in final formulations.
Q5: Can Novoperm Orange HL 70 be used in water-based systems?
A: While primarily designed for solvent-based and polymer-melt applications, HL 70 can be formulated into aqueous dispersions using appropriate surfactants and stabilization technologies—however, performance in water-based coatings or inks may require application-specific optimization.
