Optical Brightner Masterbatch "Improves brightness & whiteness."
Optical brighteners are often used to enhance the appearance of color of fabric and paper, causing a “whitening” effect; they work via a 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 This Masterbatch has the capability of re- emitting blue light with absorption of ultraviolet radiation which result into whiteness and brightness to the plastic products without any bluer tone.
