Polyphenyl ether oil

WebIn organic chemistry, ethers are a class of compounds that contain an ether group—an oxygen atom connected to two alkyl or aryl groups. They have the general formula R−O−R′, where R and R′ represent the alkyl or aryl groups.Ethers can again be classified into two varieties: if the alkyl or aryl groups are the same on both sides of the oxygen atom, then it … WebOct 21, 2024 · Compared with ADEs, polyphenyl ethers (PPEs) show significantly superior thermal and chemical stabilities, as well as radiation resistance [17,18,19,20,21]. A 5P4E (5 phenyl 4 ether)-based lubricant has been employed in gas turbine engines [22,23] and its rheologic properties have been studied in elastohyrodynamic lubrication [24,25].
