Optical Brightener KSN

Product Overview

Optical Brightener KSN is a premium-grade fluorescent whitening agent widely utilized in the polymer and textile industries. Chemically identified as 2-(4-{(E)-2-[4-(1,3-benzoxazol-2-yl)phenyl]vinyl}phenyl)-5-methyl-1,3-benzoxazole, it belongs to the bis-benzoxazole stilbene class of optical brighteners. This compound imparts a vivid, neutral-to-blue-violet white shade to synthetic materials, significantly enhancing visual brightness without altering base coloration.

Specifications

Industrial Applications

Optical Brightener KSN is specifically engineered for demanding applications in polyester fiber production and plastic manufacturing. Its molecular structure ensures exceptional compatibility with polyethylene terephthalate (PET), polypropylene (PP), and low-density polyethylene (LDPE). Key performance attributes include:

• Superior light fastness, maintaining brightness under prolonged UV exposure
• Outstanding resistance to migration, particularly critical in LDPE film applications
• High thermal stability during melt processing up to 280°C
• Neutral to blue-violet fluorescence tone for premium aesthetic quality

This additive is ideal for packaging films, synthetic textiles, engineering plastics, and household goods where long-lasting whiteness and clarity are essential.

Handling and Packaging

Supplied in 25 kg fiber drums with inner liners, Optical Brightener KSN should be stored in a cool, dry environment with the container tightly sealed to prevent moisture absorption. Standard industrial hygiene practices are recommended during handling.
