Epoxidized Soybean Oil

Epoxidized Soybean Oil (ESBO or ESO) is a bio-based plasticizer and secondary stabilizer widely used to enhance the flexibility, durability, and processability of polymer systems. Derived from natural soybean oil, ESBO provides excellent heat stability, UV resistance, and compatibility with polyvinyl chloride (PVC), making it a preferred eco-friendly alternative to traditional phthalate plasticizers. It is extensively used in PVC compounds, wire and cable insulation, flooring, films, synthetic leather, and sealants, where it improves both performance and sustainability.

ESBO also plays a vital role in adhesives, coatings, automotive interiors, and food packaging, where its renewable and non-toxic profile supports regulatory compliance and environmental initiatives. As a secondary heat stabilizer, it enhances long-term PVC performance by reducing degradation under stress and exposure. With its combination of sustainability, efficiency, and versatility, epoxidized soybean oil has become a critical raw material across industries including construction, automotive, packaging, consumer goods, and specialty chemical manufacturing.
