Q1: What is the primary chemical class of Novoperm Yellow H2G?
A: Novoperm Yellow H2G is a high-performance perylene-based organic pigment, belonging to the perylene tetracarboxylic diimide (PTCDI) family, known for exceptional thermal stability, lightfastness, and weather resistance.
Q2: Is Novoperm Yellow H2G suitable for use in food-contact plastics?
A: While Novoperm Yellow H2G is not inherently restricted for food-contact applications, its suitability depends on final regulatory approval within the specific polymer matrix, processing conditions, and end-use jurisdiction. It is commonly evaluated in polyolefins and engineering thermoplastics where high thermal stability is required.
Q3: How does Novoperm Yellow H2G perform under high-temperature processing?
A: This pigment exhibits excellent thermal stability and is routinely processed in polymers such as polypropylene, polyethylene, and engineering resins at temperatures up to 300 °C without significant decomposition or hue shift, making it well-suited for demanding extrusion and injection molding applications.
Q4: What dispersion characteristics should be expected during compounding?
A: Novoperm Yellow H2G typically requires robust dispersion energy due to its high crystallinity and strong intermolecular forces. Optimal results are achieved using high-shear compounding equipment and compatible dispersants—dosage depends on formulation requirements but generally ranges from 0.1% to 2% by weight relative to pigment loading.
