Optical Brightener :

Optical Brightener is based on bis-benzoxazole type organic derivative dispersed in poly-olefin polymer.
These kinds of Masterbatches added in polymers to decrease yellowing, improved whiteness, and to enhance the brightness of a product.
These Masterbatches function by absorbing the ultraviolet radiation and re-emitting the blue light.
Also we developed these optical brightener Masterbatches, which produce enhance whiteness and brightness of the product without giving bluer tone.
