Optical brighteners are designed to brighten colors or mask yellowing in lacquers, paints, inks, plastics, photo-processing solutions and fibers they work via a fluorescent mechanism, absorbing light in the uv spectrum and emitting it in the blue range of the visible spectrum, resulting in a brighter, fresher appearance. Our company specializes in the production and sale of fluorescent bleaching agent series products, which are widely used in plastic, printing and paper-making industry in 2010, we got the government official documents in safety supervision, environmental protection and fire protection fields. Optical brightening agent optical brightening agentsis added to many substrates to reduce yellowing, improve whiteness and enhance the brightness of the productoptical whiteners function by absorbing ultraviolet radiation and re-emitting blue light the emitted blue light will reduce the yellow color of the substrate and impart a pleasing whiter-than-white appearance. Fluorescent whitening agents (fwas) composition : members of this class of diaminostilbene sulfonate derivatives are highly conjugated molecules having planar structure and anionic charge all of these adjectives also apply to direct dyes.
Best fluorescent whitening agent for engineering plastics, especially recommended for pet and nylon very useful for improving the appearance of recycled polymers, extensively used in lldpe based master batch. Bleaching is irreversible decomposition of the fluorescent molecules because of light intensity in the presence of molecular oxygen quenching also results in reduced fluorescence intensity and frequently is brought about as a result of oxidizing agents or the presence of salts of heavy metals or halogen compounds. Jiangxi mingcheng technology development co,ltd is a high-tech chemical manufacturer, invested directly by hangzhou tidesource chemical co, ltd focus on the production of eco-friendly flame retardants and optical brightening agents. Anti-bleaching agents such as p-phenylenediamine can be used for fitc, and n-propyl gallete can be used for rhodamine use nd filters use neutral density or nd filters on the microscope to reduce light levels to the minimum needed for observation.
Fluorescent bleaching agent products are most popular in southeast asia, domestic market, and mid east you can ensure product safety by selecting from certified suppliers, including 116 with gmp, 100 with iso9001, and 46 with other certification. Introduction of fluorescent brightening agent fluorescent brightening agent also known as optical bleaches or fluorescent whitening agents that are fluorescent white dyes which absorb ultraviolet region (340 – 370 mm) light of electromagnetic region emit back to visible blue region that is at 420- 470 nm.
Uv rays (found either in sunlight or artificial light such as fluorescents) act as a bleaching agent through a complex process, uv rays transform the water found in all fabrics into hydrogen peroxide, (a common bleaching agent) that leads to the fading of dyestuffs. Preferred anti-fading agent for confocal fluorescence microscopy i was looking at commercial agents (such as vectashield), but they are a bit expensive prolong diamond is a new antifade from. Fluorescent brightener is commonly known as white dye, also known as optical brighteners, briefly called brighteners it is a colorless organic compound that can stimulate fluorescence under ultraviolet light.
