In polyester and nylon fibers, LEPUZ optical brighteners impart a pleasing whiter-than-white appearance and give more intensity to some colors as well. Because of its excellent brightening ability, good thermal stability, and compatibility with many polymers, LEPUZ OB-1 is an effective brightener for many plastics. LEPUZ OB-1 provides an excellent white, permanent color since the brightener is dissolved in the polymer or fiber during polymer manufacture. This permanence gives much better brightness retention over time versus other methods such as bleaching or surface treatment with optical brighteners. Optical whiteners function by absorbing ultraviolet radiation and re-emitting blue light. The emitted blue light will reduce the yellow color of a polymer and provide the whiter-than-white appearance.Typical PropertiesPropertyTypical ValueAppearanceYellow greenish powderSpecific Gravity @ 20ºC/20ºC1.39Melting Point359-361ºCAssay98 wt % minParticle SizePass 200 mesMain productsOptical brightener:OB-1 OB NFW MDAC(SWN) KSN KCB FP-127 CBS-XPigment:Red 122 Yellow 110 Yellow 138 Violet 23 Violet 19UV Stabilizer:783 770 944 622 292Antioxidant:168 1010 1076 245 425 BHT(264) 2246UV Absorber:1577 531 571 234 1130 360 99-2 UV-1 327 328 326 329 Our ServicesOur factory has advanced production and equipments, which can be used for testing and reprocessing to ensure the high quality and meet customers' different requirements, so that we can offer technology consultion for customers.Cooperated with outstanding shipping agent, we can supply quality and convenient shipping service.Besides, with professional staves, costomers can receive accurate and timely reply.Company InformationNANJING LEPUZ CHEMICAL CO., LTD is an ISO-certificated modernized chemical enterprise concentrating on the production, sales and service for plastic and coating additives, fine chemicals and intermediates.
