Optical Brightener KSN for Plastics | C.I. Fluorescent Brightener 368 | CAS No. 5242-49-9
Key Features
High Thermal Stability
KSN is suitable for plastic and polymer processing applications involving elevated temperatures, making it useful for a range of thermoplastic processing systems.
Effective Optical Brightening
KSN helps improve visual whiteness and brightness by compensating for unwanted yellowish tones through blue fluorescence.
Good Compatibility with Polymer Systems
KSN can be incorporated into various compatible polymer systems where improved whiteness and brightness are required.
Low-Dosage Application
KSN is generally used at relatively low addition levels to achieve optical brightening effects in compatible polymer systems.
Suitable for Synthetic Fibers
In addition to plastics, KSN can be used in compatible synthetic fiber applications, including polyester and certain other synthetic fiber systems.
