Megawhite Dt (Optical Brightener)

Supplier From Bangladesh
May-29-24

Optical brightening agents (OBAs), also known as fluorescent brightening agents (FBAs), or fluorescent whitening agents (FWAs) are chemical compounds that give a whitening effect to the fabric. They do this by absorbing light in the ultraviolet and violet region and re-emit the light in the blue region. Fluorescent activity is a short-term or rapid emission response, unlike phosphorescence, which is a delayed emission. This blue light reduces the yellow color of the substrate and gives a bright look.

At Meghmani, you will find the ideal and quality Optical Whitening Agents. Being one of the leading optical brightening agent manufacturers and suppliers, we ensure delivering only the best products.
