Optical Brightener Masterbatch

Goldmine’s Optical Brightener Masterbatch — making plastics appear cleaner, brighter and visually whiter

Optical Brightener Masterbatch is engineered to improve the perceived whiteness and brightness of plastics by leveraging high-efficiency fluorescent whitening agents.
When added to polymers, these brighteners counter yellowing, enhance surface gloss and give the product a distinctly “fresh” and “premium” visual appearance.

The Goldmine formulation provides strong whitening performance at low dosages, with excellent heat stability and compatibility with PP, PE, ABS, PS and recycled polymer blends.

From packaging films to injection molded consumer products, the result is always a brighter, cleaner final product ideal for consumer goods, packaging, films, and recycled polymer upgrades.
