Q1: What is the primary chemical class and pigment type of PV Fast Yellow H2GR?
A: PV Fast Yellow H2GR is a high-performance monoazo pigment, classified under the Colour Index (C.I.) as Pigment Yellow 83. It belongs to the azo family and is specifically engineered for excellent heat stability and lightfastness in demanding polymer applications.
Q2: Is this pigment suitable for food-contact plastics?
A: PV Fast Yellow H2GR is not certified for direct food-contact applications under major global regulatory frameworks. It is intended for non-food-contact industrial plastics, coatings, and inks where high chroma and thermal stability are required. Always consult local regulatory requirements and perform application-specific compliance testing before use.
Q3: What is the typical dosage range in polyolefin compounds?
A: In polyolefins such as PP and HDPE, PV Fast Yellow H2GR is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—depending on the desired shade strength, opacity, and processing conditions. Optimal dispersion is critical, and masterbatch dilution is commonly recommended for consistent performance.
Q4: How does PV Fast Yellow H2GR perform under high-temperature processing?
A: This pigment exhibits good thermal stability, making it suitable for standard melt-processing temperatures encountered in extrusion and injection molding of engineering thermoplastics. It maintains color integrity up to approximately 280–300 °C for short residence times, though prolonged exposure above 290 °C may lead to gradual chroma reduction.
