Optical Brighteners

Significantly improve the whiteness in both textile fibers and plastics. In polyester and nylon fibers, optical brighteners impart a pleasing whiter-than-white appearance and give more intensity to some colors as well. Because of its excellent brightening ability, good thermal stability, and compatibility with many polymers, OB-1 is an effective brightener for many plastics. OB-1 provides an excellent white, permanent color since the brightener is dissolved in the polymer or fiber during polymer manufacture. optical whiteners function by absorbing ultraviolet radiation and re-emitting blue light. The emitted blue light will reduce the yellow color of a polymer and provide the whiter-than-white appearance.

Applications : Plastics, Printing Ink and Coatings, Flexible PVC, Detergent.
