Description

Benzene-1,2,4-Tricarboxylic Acid=Trioctadecyl is a high-purity, long-chain alkyl ester derivative of trimellitic acid, designed for advanced material synthesis. This specialty chemical is valued for its ability to impart unique solubility, plasticizing, and hydrophobic properties in polymer and coating formulations. It serves as a critical intermediate for researchers and manufacturers in the polymer additives, lubricant, and specialty surfactant industries seeking to modify material performance.

Application

• As a plasticizer and compatibilizer in high-performance polymer blends, including PVC and engineering plastics.
• Key intermediate for synthesizing specialty surfactants and emulsifiers with long hydrophobic chains.
• Raw material in the production of lubricant additives and synthetic esters for industrial applications.
• Modifier for coatings and inks to enhance flexibility, adhesion, and water resistance.
• Building block for dendrimers and hyperbranched polymers in advanced material research.
• Potential use as a phase change material (PCM) precursor in thermal energy storage systems.
