• 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. Triethylene Glycol Bis(3-?tert-?butyl-?4-?hydroxy-?5-?methylphenyl)?propionate is used as a polymer antioxidant stabilizer in adhesives and polymers for food contact. Generally functions as an antioxidant in the chemistry of plastics.
