Q1: What are the key performance characteristics of Paliotol Yellow L 2140 in polymer applications?
A: Paliotol Yellow L 2140 is a high-performance monoazo organic pigment known for excellent heat stability, good lightfastness, and strong tinting strength. It demonstrates good compatibility with common thermoplastics such as polyolefins and PVC, and maintains dispersion stability under typical processing conditions like extrusion and injection molding.
Q2: Is this pigment suitable for food-contact plastics?
A: Paliotol Yellow L 2140 is not certified for direct food-contact applications under major regulatory frameworks. Its use in food packaging or containers should be evaluated case-by-case based on applicable local regulations, intended exposure conditions, and migration testing—consult BASF technical support for compliance guidance specific to your formulation and end-use.
Q3: How should Paliotol Yellow L 2140 be dispersed in polymer systems?
A: Optimal dispersion is achieved using standard compounding techniques—such as twin-screw extrusion—with appropriate screw design and temperature profile. Pre-dispersed masterbatches are widely used for consistent coloration and improved handling. Avoid excessive shear or prolonged thermal exposure beyond recommended processing windows to preserve pigment integrity.
Q4: What is the typical dosage range when using this pigment in polyolefin compounds?
A: Dosage depends on the desired shade intensity and substrate opacity, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in polyolefin-based systems. Strong tinting strength allows for economical usage while maintaining color consistency and minimal impact on mechanical properties.
