1.Product Description
Achieve Superior Whiteness with Optical Brightener ER-II – The Low-Temperature, High-Performance Brightener for Polyester and Blends.
Optical Brightener ER-II, internationally designated as Fluorescent Brightener 199:1 (C.I. 199:1), is a premium distyrylbenzene derivative engineered specifically for whitening polyester fibers and their blends at lower processing temperatures than conventional ER-I . This sophisticated non-ionic brightener features a unique molecular structure with two cyanostyryl groups attached to a central benzene ring, delivering exceptional whitening performance with a bluish-violet fluorescence .
The key advantage of ER-II lies in its lower luminance temperature requirement, enabling effective whitening at reduced processing temperatures while achieving higher whitening performance than ER-I . This translates to energy savings and gentler processing conditions for heat-sensitive substrates.
Key differentiators:
Low-Temperature Whitening: Demonstrates excellent whitening efficacy at lower processing temperatures compared to ER-I, enabling energy-efficient operations.
Superior Whitening Performance: Delivers higher whitening intensity than ER-I at optimal application conditions.
Excellent Chemical Stability: Stable with hypochlorite, hydrogen peroxide, and reactive bleaching agents, enabling one-bath whitening and bleaching processes .
Non-Ionic Character: Insoluble in water but readily soluble in organic solvents, with excellent compatibility across various polymer systems.
Good Lightfastness: Rated Grade 5 for lightfastness, ensuring long-lasting whitening effects.
Our Optical Brightener ER-II is manufactured under strict quality controls with≥98.5% purity and consistent batch-to-batch performance, meeting international quality standards for textile and plastic applications .
