CESA-bright masterbatches convert UV radiation into visible, bluish light, improving the long-term whiteness appearance of finished plastic products.
Often a brilliant appearance with a bluish undertone is desirable for thermoplastic articles, particularly for polymers with an inherently slightly yellow cast. Topical optical brighteners have typically been used to improve the surface whiteness of plastic articles and synthetic fibers.
Adding CESA-bright concentrates to the polymer itself produces much better brightness retention over time than surface treatment with topical optical brighteners.
