Description

cis-9,10-Epoxystearic Acid is a high-purity, monounsaturated fatty acid derivative featuring an epoxide functional group. This unique structure makes it a valuable and versatile chemical intermediate for synthesizing specialty polymers, lubricants, and surfactants. It is essential for manufacturers in the polymer, coatings, and specialty chemical industries seeking to develop products with enhanced flexibility, adhesion, or bio-based content.

Application

• Polymer & Resin Modification: Acts as a reactive diluent and flexibilizer in epoxy resin systems and as a monomer for polyol synthesis.
• Lubricant & Grease Formulation: Serves as a precursor for high-performance ester-based lubricants and metalworking fluids.
• Surfactant & Emulsifier Production: Used in the synthesis of non-ionic surfactants and emulsifying agents for industrial and cosmetic applications.
• Plasticizer & Stabilizer Intermediate: A key building block for creating bio-derived plasticizers and polymer stabilizers.
• Coating & Adhesive Formulations: Imparts improved adhesion and flexibility to coatings, inks, and adhesive products.
• Chemical Synthesis: A versatile intermediate for organic synthesis, including ring-opening reactions to produce diols and other derivatives.
