Q1: What is the primary chemical class and typical hue profile of GRAPHTOL 3GP 155?
A: GRAPHTOL 3GP 155 is a high-performance perylene-based organic pigment, delivering a clean, bluish red shade with excellent brightness and strong tinting strength. Its molecular structure provides inherent resistance to thermal degradation and light exposure.
Q2: Is GRAPHTOL 3GP 155 suitable for use in food-contact plastics?
A: GRAPHTOL 3GP 155 is designed for high-performance industrial applications and is not pre-qualified for direct food-contact use. Customers intending to use it in food-contact polymers must conduct full regulatory evaluation—including extraction testing and compliance verification—according to applicable regional requirements.
Q3: How does GRAPHTOL 3GP 155 perform in high-temperature polymer processing?
A: This pigment exhibits excellent thermal stability, making it suitable for demanding processing conditions such as injection molding and extrusion of engineering thermoplastics. It maintains color integrity and shows minimal decomposition up to typical processing temperatures for polyesters, polyamides, and polycarbonates.
Q4: What dispersion methods are recommended for optimal performance in masterbatches?
A: For consistent color development and maximum tinctorial efficiency, high-shear compounding—using twin-screw extruders with optimized screw configuration and residence time—is strongly recommended. Pre-wetting with compatible carrier resins and controlled temperature profiles help achieve uniform pigment distribution and minimize agglomeration.
