Product Overview
Dioctyl Sebacate (DOS) is a high-performance sebacate ester produced by esterifying castor oil–derived sebacic acid with 2-ethylhexanol. It is globally recognized for its exceptional low-temperature fluidity, thermal stability, and lubricating performance, making it a preferred choice in demanding applications.
At Nova Industries, Dioctyl Sebacate is manufactured through a precisely controlled esterification and purification process, ensuring low residual acidity, stable ester value, and consistent color. These parameters are critical for applications such as synthetic lubricants and aviation oils, where performance reliability and consistency are non-negotiable.
Compared to mineral oils and conventional plasticizers, DOS offers superior viscosity-temperature behavior, low volatility, and excellent oxidative stability. Buyers select this product when they require a bio-based, long-life ester fluid capable of performing under extreme temperature conditions and extended service intervals.
