OPTICAL BRIGHTNER

Optical brightener is based on bis-benzoxazole type organic derivative dispersed in polymer.

These masterbatches are added in polymers to reduce 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. These masterbatches are used in order to mask natural yellowing of plastics.

When it comes to color, getting it right can be a challenge. Adding color will always affect the polymer being processed, although the way in which it does so will vary from plastic to plastic, and even from color to color.

Converters are faced with choices such as using higher doses of weaker masterbatches, which facilitates an even dispersion throughout, or small quantities of a stronger masterbatch, which can offer cost advantages.
