PHILODEN Industries offers high-molecular brighteners, which find its use in Thermoplastics, Printing Inks, Lacquers and Man-made Fibers.
Optical brighteners typically work by reducing the yellowness and improving whiteness. Doing so, they help to enhance the overall brightness of any products.
PHILOWHITE OB and OB-1 are products which due to their excellent brightening ability, can be used in a wide range of polymers or any articles made of it.
These two grades, based on similar chemistries and molecular weight, just differ by their melting point and weight-loss. Regarding coloristic and polymer suitability, they are exchangeable.
