Description

Epoxidized Soya Bean Oil (ESBO) is a versatile bio-based plasticizer and stabilizer derived from natural soybean oil. This compound is critical for enhancing the flexibility, durability, and thermal stability of polymer formulations while supporting sustainable manufacturing initiatives. It is an essential raw material for manufacturers in the plastics, packaging, and coatings industries seeking reliable, non-phthalate additive solutions.

Application

• Primary plasticizer and secondary stabilizer for Polyvinyl Chloride (PVC) in wire & cable, films, and synthetic leather.
• Stabilizer and flexibilizer in adhesive and sealant formulations.
• Modifier and plasticizer for various rubber and elastomer compounds.
• Additive in paints and coatings to improve film flexibility and adhesion.
• Stabilizing agent in food-contact polymeric materials (subject to compliance with relevant regulations).
• Intermediate in the synthesis of polyols for polyurethane applications.
• Lubricant additive and viscosity modifier.

Quality Control

Our Epoxidized Soya Bean Oil is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for oxirane oxygen content, iodine value, acidity, and color. A Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance with agreed parameters.

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 product is easily oxidized; prolonged storage under an inert atmosphere (e.g., nitrogen) is recommended for optimal shelf life. Keep away from strong acids and heat sources.
