Diester lubricants, which have applications in both automotive and aviation engine oils, produced from long-chain diacids have better performance than lubricants produced from shorter chain length esters or hydrocarbon base oils. General use of long-chain diacids to produce diester lubricants has been limited due to the high cost and limited availability of long-chain diacids. However, we believe the cost efficiency associated with our long-chain diacids can produce diester lubricants that can be competitive in the market place. Our Novacid DC11 to DC14 can be used to produce lubricants.

Long-chain dicarboxylic acids react with monohydric alcohols (e.g., 2-ethylhexanol, isodecyl alcohol, trimethylolpropane) to form diesters or complex esters, which are premium base stocks for high-performance lubricants.
- Key Products: Dodecanedioic acid diesters, sebacate esters, polyol esters; aviation turbine oils, synthetic engine oils, low-temperature greases, metalworking fluids.

- Technical Advantages: High thermal/oxidative stability (low volatility at 150–200°C), excellent low-temperature fluidity (pour points down to -50°C), outstanding anti-wear/extreme pressure performance, compatibility with elastomers/seals.

- End Uses: Aerospace (jet engine lubrication), automotive (transmission fluids, differential oils), industrial (gear oils for cold climates, hydraulic fluids for high-temperature equipment).
