Description

Fatty Acids, C18-Unsatd., Dimers, Mixed Esters With Decanoic Acid, Octanoic Acid And Trimethylolpropane CAS NO 173832-39-8 is a specialized synthetic ester derived from unsaturated C18 fatty acid dimers, capric acid, caprylic acid, and trimethylolpropane. This multi-functional compound is engineered to provide excellent lubricity, hydrophobicity, and oxidative stability in demanding formulations. It is a critical raw material for manufacturers in the lubricants, coatings, and polymer industries seeking high-performance bio-based additives.

Application

• Primary component in high-performance synthetic lubricants and metalworking fluids.
• Plasticizer and compatibilizer for PVC, polyurethane, and other specialty polymers.
• Key ingredient in release agents and mold lubricants for rubber and plastic processing.
• Functional additive in industrial coatings and inks to enhance flow and surface properties.
• Base fluid for formulating environmentally acceptable lubricants (EALs) and biodegradable greases.
• Intermediate for the synthesis of specialty surfactants and emulsifiers.
