Optical Brightener OB-1 Masterbatch is a whitening masterbatch, Fluorescent whitening masterbatch, as a key additive to improve the whiteness and color of products, lies in the special effect of fluorescent whitening agent.
This kind of colorless organic compound can absorb ultraviolet light and convert it into blue-violet fluorescence, which complements the yellow light of the product itself, thus significantly improving the apparent whiteness and brightness of the product. And it is a kind of plastic granules made of fluorescent whitening agent and other auxiliary materials.
Optical Brightener OB-1 Masterbatch is an additive on plastic, mainly plays the role of whitening. Now the Optical Brightener OB-1 Masterbatch is widely used in textiles, paper, plastics, coatings, various types of injection and blow molding plastics, especially in the production of recycled materials.
