Durasyn polyalphaolefin synthetic fluids have greater film thickness at high temperatures than comparable Group I, Group II or Group III mineral oils. Exceptional low temperature viscometrics. Excellent thermal, oxidative and hydrolytic stability. Colorless and odorless, No sulfur, nitrogen or aromatics. Non-toxic, non-corrosive Uniform (engineered) molecular structure. Synthetic lubricant that is based on a polyalphaolefin (PAO) base oil. Its a type of syntetic lubricating oil that are made from the alpha olefins, which are unsaturated hydrocarbons that are produced from ethyene though a process called oligomerization. PAO's are know for their good thermal stability, low volatility nd good lubrication properties and are used in a variety of applications, including automotive and industrial lubricants. Durasyn 164 is a high performance lubrincat that is recommended for use in a range of application, including bearing, gears, compressors and hydraulic systems.
