Q1: What are the primary application areas for BASF K3840 2030?
A: BASF K3840 2030 is a high-performance organic pigment designed primarily for use in engineering thermoplastics, including polyamide (PA), polybutylene terephthalate (PBT), and polyethylene terephthalate (PET), where excellent thermal stability and dispersion behavior are required.
Q2: How does K3840 2030 perform under high-temperature processing conditions?
A: This pigment exhibits good thermal stability, enabling reliable performance during melt processing of engineering plastics at temperatures commonly encountered in injection molding and extrusion—typically up to 280–300 °C, depending on residence time and polymer matrix.
Q3: Is K3840 2030 suitable for food-contact or regulatory-sensitive applications?
A: While K3840 2030 is not marketed as food-contact compliant, it may be evaluated for specific regulated applications subject to full formulation assessment and compliance verification by the end-user. Regulatory suitability depends on final article composition, processing conditions, and applicable jurisdictional requirements.
Q4: What is the typical dosage range when using K3840 2030 in thermoplastic compounds?
A: Dosage is formulation-dependent but generally ranges from 0.1% to 2% by weight, with optimal loading determined by desired color strength, transparency requirements, and compatibility with the polymer system and other additives.
Q5: How should K3840 2030 be dispersed for best results in polymer melts?
A: For optimal dispersion, pre-mixing with the base polymer followed by high-shear melt compounding—such as twin-screw extrusion—is recommended. The pigment’s surface treatment supports efficient wetting and minimizes agglomeration during processing.
