Q1: What types of resin systems is MAB-21H compatible with?
A: MAB-21H demonstrates good compatibility with a broad range of thermoplastic and thermosetting systems, including ABS, PS, PC, PMMA, and certain polyolefin-based masterbatches. Performance in polyolefins may require optimized carrier selection or surface treatment for improved dispersion.
Q2: How should MAB-21H be dispersed to achieve optimal fluorescence intensity and uniformity?
A: For best results, use high-shear melt compounding or twin-screw extrusion at temperatures appropriate for the host polymer. Pre-drying is recommended if moisture sensitivity is a concern. Avoid excessive thermal history or prolonged residence time, which may affect fluorescent brightness.
Q3: Is MAB-21H suitable for applications requiring UV stability?
A: MAB-21H offers moderate resistance to UV-induced fading under typical indoor conditions. For extended outdoor exposure, co-stabilization with UV absorbers or HALS is recommended to maintain fluorescence performance over time.
Q4: What is the typical dosage range for achieving strong fluorescent effect in plastic articles?
A: Dosage depends on formulation requirements and desired intensity, but MAB-21H is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in the final compound—with most applications falling between 0.3% and 1.2%.
