Ob Masterbatch


UNICOM OB MASTERBATCH is useful in suppressing the yellow index of the base polymer. Hence, the end product gets a bright glossy surface. For white products, whiteness index also will increase. Optical brightners are also called Flourescent Whitening agents. These Masterbatches work via a flourescent 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.
