Description

Isooctyl Epoxyoctadecanoate is a specialized epoxidized ester derived from oleic acid, widely recognized for its role as a high-performance plasticizer and stabilizer. This compound is valued for its ability to impart excellent flexibility, thermal stability, and low volatility to polymer matrices, enhancing product durability. It is a critical material for manufacturers in the plastics, coatings, and adhesives industries seeking to improve the performance and longevity of their formulations.

Application

• Primary plasticizer and co-stabilizer for PVC (polyvinyl chloride) compounds, including cables, films, and profiles.
• Stabilizing agent in polymeric materials to prevent degradation from heat and light exposure.
• Key component in the formulation of adhesives and sealants to enhance flexibility and adhesion.
• Additive in industrial lubricants and greases to improve viscosity and stability.
• Modifier for synthetic rubbers and elastomers to optimize processing and physical properties.
• Intermediate in the synthesis of other specialty esters and polymer additives.

Quality Control

Our Isooctyl Epoxyoctadecanoate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot is tested against rigorous internal specifications, which typically include assay, epoxy content, acid value, and color. A Certificate of Analysis (COA) detailing all test results is provided with every shipment 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 light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep away from heat, sparks, and open flame. For long-term storage, consider using under an inert gas blanket such as nitrogen to maintain product integrity.
