    What is Brightening Agent OB-1 WITH CAS 1533-45-5 

    Brightening Agent OB-1 can absorb invisible ultraviolet light (wavelength range is about 360-380nm) and convert it into blue light or purple visible light with a longer wavelength, so it can compensate for the unwanted yellowish color in the matrix, and reflect more visible light with a wavelength of 400-600nm than the original incident light, so that the products appear whiter, brighter and more bright.
    It is a high-efficiency fluorescent whitening agent for polyester fiber, and is widely used in ABS, PS, hips, PC, PP, PE, EVA and rigid PVC. It has excellent whitening effect, excellent thermal stability, and few additives.
