BIOTEX® OB-1 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. BIOTEX® OB-1 is especially useful in polyester and nylon fibers, as well as in high temperature engineering plastics. BIOTEX® OB-1 is recommended to increase the whiteness of polyester and polyamide fibers as well as high temperature engineering plastics, including polycarbonates, polyesters, and polyamides (nylon). The product can also be used in styrenic and acrylic polymers.
