Fluorescent Whitening Masterbatch is a type of additive used in the plastic industry to improve the whiteness and brightness of plastic products. It is also known as Optical Brightening Agents (OBAs).

Fluorescent whitening agents are designed to absorb light in the ultraviolet range, usually in the range of 340-370 nm, and then reemit it in the blue region of the visible spectrum, typically around 430 nm. This results in a brighter, more vibrant white appearance to the plastic.

What Are Some Common Applications Of Optical Brightener Masterbatch?

Fluorescent Whitening Master batch is typically added to the base polymer during processing, and it is commonly used in applications where a bright, white appearance is desired, such as in food packaging, cosmetic packaging, and consumer goods. It can be used in a variety of plastic resins, including polypropylene, polyethylene, and PET.

Fluorescent Whitening Masterbatch is available in different grades and concentrations to meet the specific requirements of different applications. The amount of masterbatch required depends on the base polymer, physical properties desired, and the end-use of the plastic product.

How Does Optical Brightener Masterbatch Work?

Optical brightener masterbatch contains fluorescent agents that absorb non-visible ultraviolet light and radiate it back as blue light, enhancing the appearance of the plastic by making it look whiter and brighter.

How Is Fluorescent Whitening Masterbatch Different From Regular Optical Brightener Masterbatch?

Fluorescent whitening masterbatch is designed specifically to enhance the whiteness of white or light-colored plastics, while regular optical brightener masterbatch can be used on any color of plastic.
