Omnistab OB
It is a high molecular weight optical brightener / fluorescent whitening agent of the thiophenediyl benzoxazole class. OMNISTAB® OB features excellent resistance to heat, exceptional whitening properties, good light fastness and low volatility. It has a brilliant bluish cast, is readily soluble in organic solvents and features good compatibility in various substrates. Suitable for the optical brightening of polymers at all stages of processing. It is highly effective in polymer substrates such as engineering plastics such as polyesters, polycarbonate, polyamides and acrylics, thermoplastic polyurethane, polyvinylchloride, styrene homo- and copolymers, polyolefins and other organic substrates. Main applications include synthetic leather, fibers, molded articles, films and sheets as well as packaging applications. The use levels of OMNISTAB® OB range between 0.0005 – 0.0010 % in unpigmented polyolefins and 0.005 – 0.100 % in other plastics.
