Optical Brightener is a kind of important functional additive, which is a colorless organic compound, can absorb ultraviolet light and then emit blue-violet fluorescence that is visible to us.It complements the yellow light and has whitening effect.Fluorescent Brightener is widely applied in plastics,textiles, detergents and paper industries,etc.
Photoinitiator also known as photosensitizers or photocuring agent can absorb certain wavelength of energy in the ultraviolet or visible (region, producing free radicals, cations,etc., thereby triggering monomer polymerization cross-linked curing compounds.The photoinitiator has the advantages of low odor, non-toxic,no environmental pollution, good stability and long-term storage.
UV Absorber/Light stabilizer is a kind of additive for polymer products (such as plastics, rubber, paint, synthetic fiber) ,which can prolong the life of polymer products.
