Optical brighteners, also known as fluorescent whitening agents (FWAs), are critical additives that enhance the visual appeal of materials by increasing perceived whiteness and brightness. At the core of their function is a fascinating photophysical process. Fluorescent Brightener 367 (CAS 5089-22-5) is a prime example of a highly effective FWA, widely utilized across numerous industrial sectors.
NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier, provides high-quality Fluorescent Brightener 367. Its mechanism of action involves absorbing ultraviolet (UV) light, typically in the 340-370 nm range, and re-emitting this energy as visible blue light. This emitted blue light compensates for any yellow cast inherent in the material, making it appear whiter and brighter to the human eye. This phenomenon is particularly valuable in industries where visual aesthetics are a key selling point.
In the plastics industry, Fluorescent Brightener 367 is a preferred additive for a variety of polymers, including polyolefins, PVC, EVA, and PU foams. It significantly improves the whiteness of these materials, making them more attractive for consumer goods, packaging, and construction applications. For procurement managers, understanding the efficiency of this brightener is important; it is effective at low concentrations, typically ranging from 0.005% to 0.05%. When considering to buy, requesting a quote from our China-based manufacturer for bulk quantities is advisable.
Beyond plastics, Fluorescent Brightener 367 finds application in synthetic fibers and is also utilized in paints and lacquers to impart a brighter finish. Its excellent stability under light and heat ensures that the whitening effect is durable and resistant to degradation during processing and end-use. This reliability makes it a favored choice for R&D scientists developing new material formulations. NINGBO INNO PHARMCHEM CO.,LTD. stands ready to supply this critical additive with assured quality and competitive pricing.
The science behind optical brighteners like Fluorescent Brightener 367 is key to enhancing product value. By understanding how this compound works and its wide-ranging applications, industrial users can make informed decisions about incorporating it into their manufacturing processes to achieve superior visual results.
