Q1: What is the primary chemical class and typical hue profile of BASF L2140?
A: BASF L2140 is a high-performance perylene-based organic pigment, known for its strong, clean red-violet shade with excellent chroma and depth. It exhibits inherent resistance to thermal degradation and offers good lightfastness and weathering stability in demanding applications.
Q2: Is BASF L2140 suitable for use in food-contact plastics or regulated packaging applications?
A: BASF L2140 is not specifically designed or certified for direct food-contact applications. Its suitability for regulated packaging depends on final formulation, processing conditions, and compliance evaluation by the end-user against applicable regional regulations — consultation with regulatory experts and testing under intended use conditions is strongly recommended.
Q3: How does BASF L2140 perform during high-temperature processing, such as injection molding or extrusion?
A: This pigment demonstrates good thermal stability, typically maintaining color integrity up to approximately 300 °C for short residence times. Performance may vary depending on polymer matrix, shear history, and additive interactions — therefore, process optimization and compatibility testing are advised for each specific system.
Q4: What dispersion methods are recommended to achieve optimal color development and consistency?
A: For best results, BASF L2140 should be incorporated using high-shear dispersion techniques — such as twin-screw extrusion or high-speed dissolvers — especially in demanding polymer systems. Pre-dispersed concentrates or masterbatches are commonly used to ensure uniform distribution and minimize agglomeration.
Q5: What types of polymers is BASF L2140 most commonly used in?
A: It is widely employed in engineering thermoplastics including polyesters (PET, PBT), polyamides (PA6, PA66), and polycarbonate, where high thermal and light stability are required. It is also used in selected high-performance coatings and specialty inks, subject to compatibility validation.
