Description

9-Octadecenoic Acid (Z)-, Epoxidized, Isooctyl Ester is a specialized oleochemical derivative, valued for its role as a high-performance plasticizer and stabilizer. This epoxidized ester offers enhanced compatibility and resistance to extraction in polymer matrices, improving product longevity and flexibility. It is primarily sought by manufacturers in the plastics, coatings, and lubricant industries seeking to formulate more durable and sustainable products.

Application

• Primary Plasticizer for PVC and other polymers, providing excellent flexibility and low volatility.
• Stabilizer in plastic formulations, where it scavenges hydrochloric acid to prevent polymer degradation.
• Functional Additive in lubricants and greases to improve viscosity index and thermal stability.
• Co-modifier in epoxy resin systems and coatings to enhance adhesion and flexibility.
• Intermediate for the synthesis of more complex surfactants and specialty chemicals.
• Bio-based Plasticizer in eco-friendly polymer blends, replacing traditional phthalates.

Quality Control

Our 9-Octadecenoic Acid (Z)-, Epoxidized, Isooctyl Ester is manufactured under a stringent quality management system. Each batch is tested to ensure consistent purity, oxirane oxygen content, and physical properties critical for performance in demanding applications. Certificates of Analysis (COA) documenting key parameters 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, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; prolonged storage under an inert atmosphere such as nitrogen is recommended for optimal shelf life. Keep away from strong acids and organic solvents.
