Product Introduction

PAO is a hydrogenated Oligomer produced by polymerizing α-olefins (primarily C8-C12) in the presence of a catalyst, which is mainly composed of saturated hydrocarbons and wax-free.

Compared to mineral oils, PAO exhibits excellent low-temperature properties, high viscosity index (VI), low volatility and thermal stability. Classified as API Group IV base stock, PAO is widely used, especially in lubrication applications that require good stability under extreme operating conditions.
