Benetex OB Plus
2,5-thiophenediylbis(5-tert-butyl-1,3-benzoxazole)
7128-64-5
Benetex OB Plus is a heat resistant, solvent soluble, chemically stable fluorescent whitener that provides brighter looking colors.
It is used to offset the yellowness of a polymer and to yield a whiter appearance.
Optical brighteners create brilliance by absorbing UV light, modifying the wavelength of the light and then emitting the light in a fluorescent fashion.
Benetex OB Plus can also be used as a tracer in various applications and as an optical brightener in thermoplastics, coatings, printing inks, dyes, man-made fibers, waxes, fats, and oils.
