The whiteness of coating and natural painting could also be greatly improved by SP-KCB.Safety and stock:Keeping in stock as ordinary chemicals. Wear protective goggles and gloves while applying.A void direct contact with skin and eyes. Soap clean if skin contaminated.Packing:25kg / fiber drum with PE linerOptical Brightener Odyssey OB-1 （荧光增白剂OB-1）Optical brighteners are added to many materials to reduce yellowing, improve whiteness, and to enhance the brightness of a product. Odyssey OB-1 is used widely in the plastic market. Because of its excellent brightening ability,good thermal stability,and compatibility with many polymers.

The emitted blue light will reduce the yellow color of a polymer. In the presence of a whitening agent, such as TiO2, the use of Odyssey OB-1 will produce a brilliant white o r “white than white” appearance.Two primary factors affect the whiteness/yellowness of a formulation. They are the color of the base polymer and the level of brightener added. If no whitening agent, such as TiO2, is used, the level of Odyssey OB-1 required will likely be lower than when a whitening agent is preset. This level might be as little as 25-50 ppm. In determining the optimum concentration of brightener, the effect of any other UV-absorbing materials in the plastic should be considered. It is important that users perform sufficient evaluations to determine the optimum level of Odyssey OB-1 for their specific end uses.Methods of AdditionTo be effective, an optical brightener must dissolve in the polymer to which it is added. Since the typical addition levels for Odyssey OB-1 in the range of 100-400 ppm, the use of a concentrate, or masterbatch, is recommended. Concentrates are containing 1%-10% by weight of Odyssey OB-1 typical.The concentrate can be produced on an extruder using normal processing conditions for the polymer, including drying if necessary. The concentrate is then let down to typical use levels in the final formulation. Plastics compounding equipment is normally adequate for producing Odyssey OB-1 brightener formulations. The key requirement is to thoroughly disperse the brightener so that it will dissolve uniformly throughout the molten polymer. This is usually achieved most readily with a concentrate.Improving Whiteness of Recycled PolymerThe business of processing post consumer plastics and waste polymer continue to grow. These materials can be recycled into a variety of useful products, from plastic lumber to synthetic fiber. Polyester bottle polymer, polyester plastic waste, and waste fiber polymer can be recycled into polyester fiber that can be used in carpets, filling and insulation material, nonwovens, and apparel. One of the shortcomings of processing these materials is the uncertainty of the color of the source material.By using optical brighteners, the value of the recycled materials can be significantly enhanced by providing a more uniform white. Odyssey OB-1 will greatly improve the whiteness, Normal fiber applications require only 200-300 ppm in new polymer, but recycled material may require as much as 300-450 ppm. Optical brighteners are very effective in improving the appearance of the polymer or fiber. Off-class or second-quality nylon polymer can also be improved in the same way.Food Industry ApplicableOdyssey OB-1 complies with regulations for indirect food additives. Odyssey OB-1 is restricted to use as an optical brightener for all polymers at a level not to exceed 0.025% by weight of polymer and at the temperatures not to exceed 135"C(275"F).Packing:25kg / fiber drum with PE linerHomepage Chinese V ersionWelcome you to visit the website of Beijing Odyssey Chemicals Co.,Ltd.© Beijing Odyssey Chemicals Co.,Ltd.
