Optical brighteners function by absorbing ultraviolet radiation and remitting blue light. 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 Eflam OB-1 will produce a brilliant white or 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 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 OB-1 for their specific end uses.
