DowSyn AN5H

Chemical names: DowSyn AN5H, Alkylated Naphthalene Base Fluid

Product info

JIL Chemicals

DowSyn AN5H belongs to the alkylated naphthalene family of base fluids, categorized as API Group V lubricant base stocks. Alkylated naphthalenes are hydrocarbons featuring naphthalene cores with alkyl substituents, which lend superior thermal and oxidative stability. AN5H exhibits outstanding thermo-oxidative resistance and excellent hydrolytic durability, making it suitable for demanding applications. The fluid has a high flash point and relatively low volatility compared to some other base stocks. Its molecular structure promotes strong film strength and good lubricity characteristics. AN fluids also support improved seal swell and compatibility with various additives. Because of these traits, AN5H is selected when extended lubricant life and stability are critical design factors.

Usage

Application

DowSyn AN5H is used in premium automotive and industrial lubricant formulations requiring high thermal and oxidative resistance. It is common in high performance engine oils that operate under elevated temperatures and stresses. Its backbone structure and stability support gear and transmission fluids with enhanced durability. The fluid’s compatibility with key additives helps maintain performance in heavy duty and off-highway oils. Formulators may blend AN5H into industrial oils and greases where film strength and longevity are priorities. Due to its hydrolytic stability, it is also suited for applications exposed to moisture or high humidity.
