High fluorescence intensity with excellent bluing effect for superior brightness enhancement.
Outstanding thermal and light stability, maintaining performance during high-temperature processing.
Good compatibility with common polymers including polyester, polyamide, and acetate fibers.
Low volatility and minimal migration, ensuring long-term whiteness retention in finished products.
Easy dispersion in organic solvents and polymer melts, supporting efficient masterbatch and inline dosing.
Polyester fiber and filament production (e.g., PET staple fiber, textured yarn).
Injection-molded and extruded polyester packaging materials.
Textile dyeing and finishing of synthetic fabrics (e.g., polyester knits and wovens).
Engineering plastics requiring high-brightness aesthetic properties.
Recycled PET (rPET) applications where optical brightening compensates for yellowing.
