Description

Diisooctyl Glutarate is a high-purity diester plasticizer and solvent derived from glutaric acid and isooctyl alcohol. This compound is valued for its excellent solvating power, low volatility, and compatibility with a wide range of polymers and resins. It is primarily sought by formulators in the polymer, coatings, and specialty chemical industries seeking to enhance flexibility, processability, and performance in their end products.

Application

• Primary plasticizer and co-plasticizer for PVC, polyurethanes, and other synthetic polymers.
• Solvent and carrier fluid in high-performance industrial and specialty coatings and inks.
• Intermediate in the synthesis of lubricant additives and functional fluids.
• Component in adhesive and sealant formulations to improve flexibility and adhesion.
• Processing aid and viscosity modifier for various elastomers and rubber compounds.
• Additive in personal care products (e.g., sunscreens, cosmetics) as an emollient and solvent.
• Plasticizer for specialty cellulose-based plastics and nitrocellulose lacquers.
• Chemical intermediate for further organic synthesis in pharmaceutical and agrochemical manufacturing.
