Cesa™ Bright 荧光增白剂
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.
