Masterox® Optical Brightener

Enhances whiteness and brightness in polymers.


A recent addition to our Masterox® range, Masterox® Optical Brightener is specifically formulated to enhance whiteness and brightness in polymers. Optical brightening is paramount to the appearance of the final product, reducing the discolouration of polymers during the manufacturing process.

Here at Birch Chemicals, the quality of our Masterox® Optical Brightener range is ensured by our commitment to innovation and the highest standards of environmental responsibility.
