Optical Brightener Masterbatches

Optical brightener is also called Fluorescent Whitening agents. These Masterbatches are added in polymers to reduce yellowing, improved whiteness, and to enhance the brightness of a product. These Masterbatches work via a fluorescent mechanism which absorbs light in the UV spectrum and emits light in the blue region of visible spectrum to yield a brighter and fresher appearance.

Mode of Action: The tendency of many Plastic materials to yellow is due to degradation by UV or visible light/Processing. The breakdown products absorb blue light, giving a yellow appearance in daylight. 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. Optical brightener masterbatch will actually appear brighter than the light which strikes them with such qualities. it is not surprising that optical brighteners are found in numerous applications.
