Optical Brightener Masterbatches

OUR OFFERING

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. SIVA 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.

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.
