Optical Brighteners / Whitening Agents

DOUBLETEX optical brighteners are additives that impart brightness to polymers and intensify the degree of whiteness. These whitening agents 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. Optical brighteners are used in engineering plastics like thermoplastic polyurethanes, polyvinylchlorides (PVC), styrene homo- and copolymers and polyolefins among others.

  • DOUBLETEX 127 is a high performance optical brightener for polymers. It appears as a yellowish fine powder. As an optical brightener, DOUBLETEX 127 absorbs invisible ultraviolet light in the sunlight or artificial light and converts them to visible blue-violet light. Accordingly, when treating with DOUBLETEX 127, the polymers will have a snow-white outlook compared to pale yellow without treatment.
