Irganox 1135 Benzenepropanoic acid, 3,5-bis (1,1-dimethyl-ethyl)4-hydroxy-C7-C9 branched alkyl ester 125643-61-0 Ciba Antioxidants >> Phenolic PU - Prepolymers ADHESIVE IRGANOX 1135 is a 100% active, liquid hindered phenolic antioxidant for polyols, polyurethanes, and other polymers. IRGANOX 1135 is an excellent antioxidant which may be used in a variety of polymers. For the stabilization of polyurethane flexible slabstock foams, IRGANOX 1135 prevents the formation of peroxides in the polyol during storage, transport, and further protects against scorching during foaming. IRGANOX 1135 offers excellent antioxidant performance with the convenience of a pumpable liquid. Because of its low volatility and excellent compatibility, IRGANOX 1135 is particularly well suited to use in forced air cooling processes for polyurethane. The low volatility and excellent compatibility 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 ITRGANOX 1135 make it perfect fit where neat liquids, emulsions, suspensions, solutions or melts are an integral part of polymer manufacturing and processing. IRGANOX 1135 can be added before, during or after polymerization. It is easily emulsifiable. The performance of IRGANOX 1135 can be further enhanced by using it in combination with other phenolic antioxidants, substituted aromatic amines, such as Irganox 5057, and/or with costabilizers as well as light stabilizers. 100% active, liquid hindered phenolic antioxidant. Used in a variety of polymers. Possesses low volatility, very good compatibility and is easily emulsifiable. Can be used in combination with other phenolic antioxidants, substituted aromatic amines, costabilizers and light stabilizers. Use level : 1500-5000 ppm.
