| Antioxidant 1135 Chemical Properties |
| Antioxidant 1135 Usage And Synthesis |
| Physical properties | | Characterization | Antioxidant 1135 is a 100 % active, liquid sterically hindered phenolic antioxidant for polyols, polyurethanes, and other polymers.
| | Application | Antioxidant 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.
| | Features/benefits | Antioxidant 1135 offers excellent antioxidant performance with the convenience of a pumpable liquid. Due to its low volatility and excellent compatibility, Irganox 1135 is particularly well suited to be used 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 vola-tility of Irganox 1135 make it a 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.
| | Product forms | colorless to slightly yellow liquid | | Health & Safety | Antioxidant 1135 exhibits a very low order of oral toxicity and does not present any abnormal problems in its handling or general use. Detailed information on handling and any precautions to be observed in the use of the product(s) described in this leaflet can be found in our relevant health and safety information sheet.
| | Guidelines for use | Typical use levels are between 0.15 % and 0.5 %. Antioxidant 1135 can be
pumped or poured for ease of handling and efficient incorporation. It is easily
emulsifiable. Antioxidant 1135 can be added to the process stream dissolved,
dispersed, or as a pure liquid. The performance of Antioxidant 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
(e. g. phosphites, phosphonites, thioethers, hydroxylamines), as well as
light stabilizers (e. g. UV-absorbers, hindered amines). Performance data are
available. | | Uses | Antioxidant 1135 is a benzenepropanoic acid, 3,5-bis (1,1-dimethyl-ethyl)-4-hydroxy-C7-C9 branched alkyl esters. It is 100% active, hindered phenolic primary antioxidant for processing and long-term thermal stabilization. Antioxidant 1135 prevents the formation of peroxides in the polyol during storage, transport, and further protects against scorching during foaming. Its low volatility and excellent compatibility helps to prevent fogging in automotive applications and to prevent staining of textiles (e.g. furniture, carpeting, head rests etc.). Used for the stabilization of polyurethane flexible slabstock foams. Its typical use levels are between 0.15-0.5%.
| | Description | Antioxidant 1135 is hindered phenolic primary antioxidant for processing and long-term thermal stabilization. Used for the stabilization of polyurethane flexible foams. Its typical use levels are between 0.15 % and 0.5 %. | | Uses | Octyl-3,5-di-tert-butyl-4-hydroxyhydrocinnamate (cas# 125643-61-0) is an intermediate in synthesizing 7,9-Di-tert-butyl-1-oxaspiro[4.5]deca-6,9-diene-2,8-dione (D493755), an antioxidant naturally found in aerial parts of Gmelina asiatica Linn (Verbenaceae). It is also found in essential oils of some Stachys species from Mediterranean area. It is an impurity of Irganox used in the food packaging. | | Flammability and Explosibility | Nonflammable |
