Optical Brighteners / Whitening Agents

Whitening agents / optical brighteners are additives that impart brightness to polymers and intensify the degree of whiteness. These agents function on the basis of the ‘fluorescence effect’; they absorb light in the UV spectrum and emit light in the blue region of the visible spectrum to yield a brighter and fresher appearance to the plastic. Whitening agents / optical brighteners find uses in engineering plastics like thermoplastic polyurethanes, polyvinylchlorides (PVC), styrene homo- and copolymers and polyolefins among others.
