Optical Brighteners

Cesa™ Bright Optical Brighteners

Retains Brightness

Cesa™ bright masterbatches convert UV radiation into visible, bluish light in order to improve the long-term, white appearance of finished plastic products.

A bluish undertone is often desirable for thermoplastic articles, particularly for polymers with a slightly yellow cast. Topical optical brighteners have 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.
