YINOX 1135 is an excellent antioxidant which may be used in a variety of polymers. For the stabilization of polyurethane flexible slabstock foams, YINOX 1135 prevents the formation of peroxides in the polyol during storage, transport, and further protects against scorching during foaming. YINOX 1135 offers excellent antioxidant performance with the convenience of a pumpable liquid. Because of its low volatility and excellent compatibility, YINOX 1135 is particularly well suited to use in forced air cooling processes for polyurethane. The low volatility and excellent compatibilty also helps to prevent fogging in automotive applications and to prevent staining of textiles (e.g. furniture, carpeting, head rests, etc.). The liquid nature and low volatility of YINOX 1135 make it a perfect fit where neat liquids, emulsions, suspensions, solutions or melts are an integral part of polymer manufacturing and processing. YINOX 1135 can be added before, during or after polymerization.
