Plastic Auxiliary Agents Optical Brightener OB-1
In China, fluorescent brighteners were first classified as printing and dyeing auxiliary products, and then classified as dye products. Due to its unique properties and large amount of demand, it has been separated from the above two industries and has become a separate class of fine chemical products. The first largest user of domestic fluorescent brighteners is detergents, the second largest user is paper, and textiles are the third largest user.
Product Introduction:
Optical Brightener (OB-1) is a heat resistant and chemically stable fluorescent whitener that increases whiteness and provides brighter looking colors. It is used to offset the yellowness of a polymer and to yield a whiter appearance. Optical brighteners create brilliance by a fluorescence process involving absorption of invisible UV light and emission of visible blue light. OB-1 is especially useful in polyester and nylon fibers as well in high temperature engineering plastics.
Except Optical Brightener,we can also supply Pvc Resin,Pet Resin, Titanium Dioxide, Carbon Black, Iron Oxide Pigments,PP Resin, DOP 99.5%,PVC Paste Resin etc.If any demands you may have,welcome to contact with us.
