Benetex OB-1

Overview

Benetex OB-1 (1533-45-5) is a heat resistant and chemically stable fluorescent whitener that increases  whiteness and 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 a fluorescence process involving absorption of invisible UV light and emission of visible blue light.  Benetex OB-1 is especially useful in polyester and nylon fibers, as well as in high temperature engineering plastics.
