Description

Propane-1,2,3-Triyl Tris[3-(2-Acetoxyoctyl)Oxiran-2-Octanoate] is a specialized, high-molecular-weight ester derivative of epoxidized fatty acids, offering unique reactivity and plasticizing properties. This compound matters for formulators seeking advanced polymeric additives that enhance flexibility, stability, and processing characteristics in demanding environments. It is primarily needed by manufacturers in the polymer, coatings, and specialty chemical industries for developing high-performance materials.

Application

• Polymer Plasticizer: Acts as a secondary plasticizer and stabilizer in PVC, polyurethanes, and other polymer systems to improve flexibility and reduce migration.
• Epoxy Resin Modifier: Used as a reactive diluent or flexibilizer in epoxy formulations for coatings, adhesives, and composites.
• Lubricant Additive: Serves as a high-performance additive in synthetic lubricants and greases to enhance viscosity index and thermal stability.
• Coalescing Agent: Facilitates film formation in water-based paints and coatings by temporarily plasticizing polymer particles.
• Crosslinking Agent: Utilized in the synthesis of crosslinked polymers and elastomers due to its multiple reactive sites.
• Adhesive Formulation: Imparts tack and improves low-temperature performance in pressure-sensitive and structural adhesives.

Quality Control

Our Propane-1,2,3-Triyl Tris[3-(2-Acetoxyoctyl)Oxiran-2-Octanoate] is produced under a rigorous quality management system. Each batch is tested to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as epoxide value, acid value, and moisture content 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 temperatures between 15-25°C (59-77°F). This product is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) when in partially used containers to prevent degradation. Keep away from strong oxidizing agents, acids, and bases.
