Lihat Profil SellerHigh-performance optical brightener for enhanced whiteness and brightness in plastics and textiles
Powder OB AD 280 is a highly efficient optical brightener formulated to impart exceptional whiteness and fluorescence to synthetic polymers, fibers, and paper products. Designed for use in polyolefins, polyesters, and other thermoplastics, this additive absorbs ultraviolet light and re-emits it as visible blue light, effectively counteracting yellowing and improving visual appeal. Its fine powder form ensures excellent dispersion and compatibility in both melt and solution processing.
