Optical brightener masterbatches are commonly used in the polymer industry to reduce the yellow tint of products, enhance their whiteness, and increase their brightness. These masterbatches work through a fluorescent mechanism, where they absorb light in the UV spectrum and emit light in the blue region of the visible spectrum, resulting in a brighter and fresher appearance. Specifically, optical brightener MB is utilized to modify the whiteness, brightness, and reduce the yellowness of plastic products without any bluish undertones.
This masterbatch is capable of re-emitting blue light when exposed to ultraviolet radiation. By incorporating optical brightener masterbatch, the color visibility of products is improved, resulting in attractive colored articles with a smooth and glossy surface. Additionally, the high whiteness and reduced yellowness without increasing bluish tones, along with the UV radiation absorption, contribute to the creation of an attractive finished product.
