Q1: What is the primary application field for BASF L3671HD Pigment?
A: BASF L3671HD Pigment is specifically engineered for use in high-performance thermoplastic applications, particularly where excellent heat stability, low volatility, and consistent color development are required—such as in engineering plastics used for automotive interior components and durable consumer goods.
Q2: Is BASF L3671HD Pigment suitable for food-contact plastics?
A: While L3671HD exhibits favorable thermal and migration behavior in polyolefins and polyesters, it is not pre-approved for food-contact applications under major global regulatory frameworks. Customers must conduct full regulatory assessment—including extractables testing and compliance verification—based on their specific formulation, processing conditions, and end-use requirements.
Q3: How does L3671HD perform during high-temperature processing, such as injection molding of PBT or PPS?
A: L3671HD demonstrates robust thermal stability up to typical processing temperatures of engineering thermoplastics (e.g., 260–290 °C), with minimal color shift or degradation. Its molecular design supports retention of chromatic strength and hue consistency even under extended residence times in hot runners or extruders.
Q4: What dispersion support is recommended for optimal incorporation into polymer matrices?
A: For best results, L3671HD is typically supplied as a masterbatch or used with standard compounding techniques—such as twin-screw extrusion using optimized screw profiles and moderate shear. Pre-dispersed grades or compatibilized carrier systems may further enhance distribution uniformity, especially in demanding thin-wall or high-gloss applications.
