Optical Brightener OB1
IntroductionOptical brightener OB1, a fluorescent whitening agent, is especially suitable for the molding of various plastics and plastic products at high temperature. It has good properties of heat resistance, light resistance and chlorine bleach, so it is also ideal for the whitening effect of polyester fiber blended fabric with cotton and other fibers, and can be used for the whitening of polyester stock solution.
Technical parametersC.I.:393CAS NO.:1533-45-5Appearance: bright yellow crystalline powderMelting point: 357-360 ℃Purity: 98.50% or higherMaximum uv absorption wavelength: 374nmMaximum uv absorption wavelength: 434nmUsage:The Optical brightener OB1 is mixed well with the materials with the weight of 0.01-0.05% of the plastic or polyester grain before the plastic products are formed and processed or the polyester fiber is drawn.Performance characteristics: Optical brightener OB1 is an excellent oxazole whitening agent, insoluble in water, stable performance, good heat resistance, sun resistance, chlorine resistance and migration resistance, etc.Scope of application: Optical brightener OB1, especially high temperature resistant, mainly used for whitening by hot-melt rolling and dyeing, suitable for whitening polyester fiber and polyester blended fabric with cotton and other fibers.This product can also be used for plastic whitening such as ABS, PS, HIPS, PA, PC, PP, EVA and hard PVC, etc. The whiteness will also be significantly improved when OB – 1 is added to polyamide fiber, nylon and polyester.After adding OB – 1 to the recycled polyester waste, bottle material and chips, the recycled material will appear whiter and the chrominance in different recycled materials will become more consistent.
