ESBO — Epoxidized Soybean Oil
ESBO — Epoxidized Soybean Oil.
ESBO is a nontoxic plasticizer and stabilizer produced from high-quality natural soybean oil. It is particularly compatible with PVC, offering low volatility and mobility, high thermal and light stability, and good resistance to water and oil. These properties improve the mechanical strength, weather resistance, and electrical performance of finished products. Internationally recognized as a safe chemical aid for food contact applications. Soluble in hydrocarbon compounds, ketones, esters, and higher-grade alcohols. Applications: Food packaging, medical ware, films, sheets, tubes, fridge seals, artificial leather, floor leather, wire & cable, plastic wallpaper, printing ink, oil paint, coatings, synthetic rubber, liquid compound stabilizers
