Q1: What is the primary chemical class of Hostaperm Violet P-RL?
A: Hostaperm Violet P-RL is a high-performance perylene-based organic pigment, belonging to the perylene diimide family, known for exceptional lightfastness, thermal stability, and resistance to migration in demanding polymer applications.
Q2: Is this pigment suitable for food-contact plastics?
A: Hostaperm Violet P-RL is not approved for direct food-contact applications under major global regulatory frameworks. It is intended for non-food-contact industrial and decorative uses, such as automotive interior parts, technical films, and general-purpose engineering thermoplastics.
Q3: Which polymers is Hostaperm Violet P-RL most commonly used in?
A: This pigment demonstrates excellent compatibility and dispersion stability in polyolefins (PP, PE), polyesters (PET, PBT), and polycarbonate. It is less suited for highly polar or hydrophilic systems such as nylon or ABS without tailored surface treatment.
Q4: How does Hostaperm Violet P-RL perform under high-temperature processing?
A: The pigment exhibits outstanding thermal stability, retaining its violet hue and performance characteristics during standard melt processing of polyolefins and engineering plastics up to approximately 300 °C, making it suitable for extrusion, injection molding, and film blowing.
Q5: What is the typical dosage range for achieving strong coloration?
A: Dosage depends on formulation requirements and desired opacity, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—to achieve intense, clean violet shades with good tinctorial strength and minimal impact on mechanical properties.
