RF5057 Butyl Octyl Diphenylamine
Product Introduction:

RF5057 Butyl Octyl Diphenylamine refers to an outstanding high-temperature antioxidant, which provides excellent thermal stability, superior high-temperature anti-oxidation performance under high temperature, good oil solubility as well as favorable compatibility with other additives. It is widely used in the formulations of various premium internal combustion engine oil, industrial oil applications including thermal oil, high-temp chain oil, hydraulic oil, compressor oil and turbine oil, lubricating grease as well as fuel oils. The distribution of different alkyl substitutes is reasonable and controllable, and the free amine is lower than 1%. It offers better performance when combining with phenolic ester antioxidant. The recommended treat rate is 0.3-0.5% (m%).
