Description

9-Octadecenoic Acid (Z)-, Butyl Ester, Epoxidized is a specialized oleochemical derivative, functioning as an epoxidized fatty acid ester. This compound is valued for its role as a reactive intermediate and a bio-based plasticizer or stabilizer, offering a more sustainable alternative to traditional petrochemical additives. It is primarily needed by manufacturers in the polymer, lubricant, and specialty chemical industries seeking to modify material properties such as flexibility, thermal stability, and adhesion.

Application

• As a bio-based plasticizer and stabilizer for PVC and other polymers to enhance flexibility and heat resistance.
• As a reactive diluent and intermediate in the synthesis of polyols for polyurethane coatings and adhesives.
• As a lubricant additive to improve viscosity index and oxidative stability.
• In the formulation of environmentally friendly epoxy resin systems and cross-linking agents.
• As a surface modifier and coupling agent in composite materials and pigment preparations.
• In the production of specialty surfactants and emulsifiers for industrial applications.

Quality Control

Our 9-Octadecenoic Acid (Z)-, Butyl Ester, Epoxidized is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity and performance. Certificates of Analysis (COA) detailing key parameters such as epoxide content, iodine value, and acid value are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). As this material is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize moisture uptake.
