Optical Brightener OB-1 TDS

Optical Brightener OB-1 TDS is a heat resistant and chemically stable optical brightener that increases whiteness and provides brighter looking colors. Optical Brightener OB-1 (TDS) is used to offset the yellowness of a polymer and to yield a whiter appearance. Optical brighteners OB-1 (TDS) create brilliance by a fluorescence process involving absorption of invisible UV light and emission of visible blue light. Optical Brightener OB-1 (TDS) is useful in polyester and nylon fibers as well in high temperature engineering plastics.
