Description

Fettsuren, C18-Ungesttigt, Trimerisiert, 2-Ethylhexylester is a specialized, high-performance oleochemical derivative, specifically the 2-ethylhexyl ester of trimerized unsaturated C18 fatty acids. This compound is valued for its excellent solvency, plasticizing properties, and enhanced thermal stability compared to its monomeric counterparts, making it a critical functional additive in advanced formulations. It is primarily sought by manufacturers in the polymer, lubricant, and specialty chemical industries seeking to improve product flexibility, compatibility, and processing characteristics.

Application

• As a secondary plasticizer and compatibilizer in PVC, synthetic rubber, and other polymer systems to enhance flexibility and low-temperature performance.
• As a high-boiling solvent and carrier in industrial lubricants, greases, and metalworking fluids.
• As a key intermediate and building block for synthesizing more complex surfactants, emulsifiers, and corrosion inhibitors.
• As a viscosity modifier and tackifier in adhesive and sealant formulations.
• As a lubricity additive in coatings and inks to improve flow and surface finish.
• In the formulation of specialty cleaning and degreasing agents for industrial maintenance.
