Q1: What types of resin systems is FWB-203 compatible with?
A: FWB-203 demonstrates good compatibility with a broad range of thermoplastic and thermosetting polymers, including ABS, PS, PC, PMMA, PVC, and epoxy-based systems. Performance may vary depending on processing temperature and residence time, so preliminary compatibility testing is recommended for each specific formulation.
Q2: How stable is FWB-203 under UV exposure and thermal processing?
A: FWB-203 offers enhanced thermal stability compared to conventional fluorescent pigments and retains strong fluorescence after standard injection molding and extrusion processes. While it provides improved UV resistance, prolonged direct UV exposure—especially in outdoor applications—may gradually reduce intensity over time; co-stabilization with UV absorbers or HALS is advised for extended service life.
Q3: Is FWB-203 suitable for applications requiring regulatory compliance for food contact or toys?
A: FWB-203 is not pre-certified for food-contact or toy safety regulations (e.g., FDA 21 CFR, EU Plastics Regulation, or EN71-3). Its suitability depends on final formulation, migration behavior, and end-use conditions. Customers must conduct full regulatory evaluation—including extractable analysis and toxicological assessment—prior to use in regulated applications.
Q4: What is the typical dosage range for achieving optimal fluorescence intensity?
A: Optimal loading generally ranges from 0.1% to 2% by weight, depending on polymer type, desired brightness, part thickness, and processing method. Due to its high chroma and strong fluorescence, FWB-203 is typically used at low concentrations—excessive dosage may lead to aggregation or reduced transparency without proportional gain in performance.
