Q1: What is the primary function of BASF L2990HD RA Pigment in polymer systems?
A: BASF L2990HD RA Pigment is a high-performance, heat-stable red pigment designed for coloring engineering thermoplastics and thermosets. Its key role is to provide consistent, vibrant red hue with excellent dispersion characteristics and resistance to thermal degradation during high-temperature processing such as injection molding or extrusion.
Q2: Which polymer matrices is BASF L2990HD RA Pigment typically compatible with?
A: This pigment demonstrates good compatibility with a range of high-performance polymers including polyamide (PA6, PA66), polyphenylene sulfide (PPS), polyetherimide (PEI), and polyetheretherketone (PEEK). It is formulated to withstand the demanding processing conditions of these resins without significant color shift or decomposition.
Q3: How should BASF L2990HD RA Pigment be incorporated into a polymer formulation?
A: It is typically supplied as a dry powder or masterbatch concentrate and can be introduced via standard compounding methods—such as twin-screw extrusion—or direct addition in batch mixing. For optimal dispersion and color uniformity, pre-mixing with carrier resin or use of high-shear equipment is recommended. Dosage depends on formulation requirements but generally ranges from 0.1% to 2% by weight.
Q4: Does BASF L2990HD RA Pigment meet regulatory requirements for food-contact or medical applications?
A: BASF L2990HD RA Pigment is not specifically certified for food-contact or medical device applications. Customers requiring compliance with food safety or biocompatibility regulations must conduct their own due diligence—including full formulation testing and regulatory review—as suitability depends on final part geometry, processing history, and end-use conditions.
