Optical brightener is a fluorescent dye, or white dye, and it is also a complex organic compound. Optical brightener characteristic is that it can absorb UV light and radiate the visible blue light, so that the dyed substance can obtain a sparkling effect similar to fluorite, making the substance visible to the naked eye very white.
Optical brightener is a kind of color conditioning agent, which has the effect of whiting and brightening. Optical brightener is widely used in many fields such as plastics ,paper making, textile, detergent and so on.
Many industries are now beginning to use optical brighteners, such as paper, plastic, leather, and detergent. At the same time, fluorescent whitening agents are also used in many high-tech fields, such as: fluorescence detection, dye lasers, anti-counterfeiting printing, etc., and even high-sensitivity film for high-altitude photography. In order to improve the sensitivity of the photosensitive latex, fluorescence will also be used Brightener.
Optical brightener hs code 32042000 can be widely used in PVC, PS, ABS, PE, PP and other plastics.
