Q1: What are the key performance advantages of Paliogen Blue L 6360 compared to conventional phthalocyanine blues?
A: Paliogen Blue L 6360 offers significantly enhanced thermal stability and superior resistance to migration in polymer melts, particularly in demanding applications such as polyolefin coloring and high-temperature masterbatches. Its molecular structure provides improved lightfastness and weathering resistance without sacrificing dispersibility.
Q2: Is Paliogen Blue L 6360 suitable for use in food-contact plastics?
A: Paliogen Blue L 6360 is designed for non-food-contact applications. It is not approved for direct food-contact use under major global regulatory frameworks. For food-safe coloring, BASF recommends evaluating alternative pigments specifically certified for such applications.
Q3: How does this pigment perform in high-clarity polypropylene films?
A: Paliogen Blue L 6360 delivers excellent transparency and minimal haze in thin-gauge polypropylene films when properly dispersed. Its fine particle size distribution and low agglomeration tendency support high clarity, making it well-suited for premium packaging and technical film applications.
Q4: What dispersion methods are recommended for optimal performance in engineering thermoplastics?
A: High-shear compounding—such as twin-screw extrusion with optimized screw profile and residence time—is strongly recommended. Pre-dispersed concentrates or liquid preparations may further enhance uniformity in sensitive systems like polycarbonate or PBT. Avoid excessive thermal stress during processing to preserve pigment integrity.
