| Questions And Answer | Back Directory | [Characterization]
Antioxidant 245 is a sterically hindered phenolic antioxidant particularly suitable for organic substrates. It protects the substrates against thermo-oxidative degradation during manufacturing, processing and end-use. Antioxidant 245 is odorless, of low volatility, has a good color stability and exhibits high extraction resistance.
| [Physical Properties]
 | [Applications]
Antioxidant 245 is effective in styrene polymers, particularly impact modified polystyrenes, ABS, MBS, SB and SBR-latices as well as in POM homo- and copolymers. It is also very useful for the stabilization of polyurethanes, polyamides, thermoplastic polyesters, PVC and other polymers. In addition to imparting thermostability to the finished polymer Antioxidant 245 is effective as chain stopper during PVC polymerization.
| [Features/benefits]
Antioxidant 245 can be used in combination with other additives such as costabilizers (e.g. thioesters, phosphites, phosphonites, lactones), light stabilizers, and other functional stabilizers. The effectiveness of the blends of Antioxidant 245 with IRGAFOS 168 (Irganox B-blends) is noteworthy.
| [Guidelines for use]
Already 0.05 – 0.1 % of Antioxidant 245 provides long-term thermal stability tothe polymer. Concentrations up to 1.0 % can be used depending on the substrate and the requirements of the end application.
| [Uses]
Antioxidant 245 is an ethylenebis (oxyethylene) bis-(3-(5-tert-butyl-4-hydroxy-m-tolyl)-propionate). It is an antioxidant for processing and long-term thermal stabilization. It has low volatility, good color stability and is odorless. Exhibits high extraction resistance. Antioxidant 245 protects the substrates against thermo-oxidative degradation during manufacturing, processing and end use. It is compatible with styrene polymers including polystyrenes, ABS, MBS, SB and SBR as well as POM homo-and copolymers. Also compatible with polyurethanes, polyamides, thermoplastic polyesters, PVC and other polymers. It is effective as chain stopper during PVC polymerization. Its recommended dosage level is 0.05-0.1% for long-term thermal stability. Concentrations up to 1.0% can be used depending on the substrate and the requirements of the end application.
| [Health & Safety]
Antioxidant 245 exhibits a very low order of oral toxicity and does not presentany abnormal problems in its handling or general use.
