Optical Brightener EBF

Optical Brightener EBF is a high purity fluorescent brightener with a blue undertone and is used to reduce the yellowing effect and achieve a brighter, clearer appearance, especially in plastics such as polyolefins, PVC, PS and ABS. This highly thermally stable additive improves product quality in terms of both aesthetics and performance by providing maximum whiteness with low dosages. Thanks to its UV absorption properties, it also strengthens resistance against external factors.
