Q1: What is the primary application area for BASF K8740LW Pigment?
A: BASF K8740LW Pigment is a high-performance, low-migration organic pigment specifically developed for coloration of polyolefin-based food contact materials, including packaging films, containers, and caps—where regulatory compliance and thermal stability during processing are critical.
Q2: Is BASF K8740LW Pigment suitable for use in polypropylene (PP) and polyethylene (PE) compounds?
A: Yes, K8740LW is engineered for excellent dispersion and compatibility in both PP and PE matrices, offering good thermal stability up to typical melt-processing temperatures and minimal plate-out during extrusion or injection molding.
Q3: How does K8740LW differ from standard pigment grades in terms of migration control?
A: K8740LW features a specially optimized particle size distribution and surface treatment that significantly reduces extractable and migratable fractions in fatty food simulants, supporting compliance with global food contact regulations when used within recommended dosage ranges.
Q4: What is the typical dosage range for K8740LW in polyolefin applications?
A: Dosage depends on formulation requirements and desired shade intensity, but K8740LW is generally used at low concentrations—typically ranging from 0.1% to 2% by weight—due to its high tinting strength and efficient dispersion behavior.
