Product Description
Fluorescent Brightener FBA 368 is a high-performance optical brightener belonging to the thiophene derivative class, chemically known as a specific bis-benzoxazolyl thiophene compound. It is a highly efficient whitening agent primarily designed for applications in plastics and synthetic polymers. It operates by absorbing ultraviolet light and re-emitting it as intense, bright blue-violet visible light, effectively masking inherent yellowness and significantly enhancing the whiteness, brightness, and overall visual appeal of the substrate.
Application
It is used in thermoplastic plastics PVC, PE, PP, PS, ABS, SAN, SB, CA, PA, PMMA, acrylic resin, polyester fiber paint, coating the brightening of printing ink.
Storage
Store in a cool, dry place away from direct sunlight.
