FAQs
What processing methods are suitable?
Optical brightener masterbatch can be used in extrusion, injection molding, film blowing, and sheet production.
What industries commonly use optical brightener masterbatch?
They are widely applied in industrial plastics, food packaging materials, decorative plastic products, and agricultural plastic films.
Can Rongfeng provide customized masterbatch solutions?
Yes. Rongfeng can develop customized formulations based on different polymer materials and production requirements.
What is an optical brightener masterbatch?
Optical Brightener Masterbatch is a concentrated plastic additive containing optical brightening agents (OBAs), also known as fluorescent whitening agents. It is used during plastic processing to reduce yellowing and improve the perceived whiteness and brightness of finished plastic products.
How do optical brighteners work?
Optical brighteners function through a process called fluorescence. They absorb ultraviolet and violet light (typically around 340–370 nm) and re-emit it as blue light (around 420–470 nm).
Because blue light counteracts the natural yellow tint found in many polymers, this optical effect creates a cleaner, brighter, and more vibrant appearance in plastic materials.
