Description

Diisotridecyl Dodecanedioate is a high-performance, synthetic diester derived from dodecanedioic acid. This compound is valued for its exceptional stability and lubricating properties under demanding conditions. It serves as a critical base fluid and additive in the formulation of advanced lubricants, plasticizers, and functional fluids for industries requiring reliable performance with strong acids and organic solvents.

Application

• Synthetic Lubricant Base Stock: Used in high-performance engine oils, compressor oils, and gear oils where thermal and oxidative stability are paramount.
• Specialty Plasticizer: Imparts low-temperature flexibility and durability to polymers, particularly in applications involving harsh chemical environments.
• Functional Fluid Additive: Enhances the lubricity and stability of metalworking fluids, hydraulic fluids, and heat transfer fluids.
• Chemical Processing Aid: Acts as a solvent or carrier in formulations that are resistant to strong acids and organic solvents.
• Grease Formulation: A key component in synthetic greases designed for extended service life in extreme temperatures and corrosive conditions.
