Optical Brightener Masterbatch (also known as fluorescent whitening agents) is added in polymers to reduce yellowing, improved whiteness, and to enhance the brightness of a product. These masterbatches are not only has an excellent composition of bis-benzoxazole type organic derivative and poly-olefin polymer, they are also responsible for minimizing the yellowing of end product.

With the capability of re-emitting blue light with absorption of ultraviolet radiation, this masterbatch supplies a full line of optical brighteners for both water soluble and solvent soluble applications. Our OB masterbatch is specifically developed for a multitude of polymer and resin systems to ensure you of the best possible performance.
