Description
We manufacture a wide range of optical whitening agent that is used in a variety of papers, particularly in papers having high whiteness. Consequently, the papers have a bright fluorescent appearance under UV illumination.
Fluorescent dyes such as umbelliferone and stilbenes are the most familiar chemicals having the whitening property. They attract energy in the UV fraction of the spectrum and re-emit it in the blue fraction of the visible spectrum. After being treated with an optical whitener, a white surface appears whiter as it discharges additional visible light than shines on it. The yellow and brown tones of the material are hided by the blue light released by the whitener, making the material appear whiter.
