Epoxidized Soybean Oil (ESBO) is a crucial plasticizer used in industries like plastics and rubber. It softens polymers by reducing their glass transition temperature, increasing flexibility. ESBO's advantages include compatibility with PVC, stability against light and heat, and resistance to migration. It works well with metal stabilizers like zinc-calcium compounds. However, it can crystallize at low temperatures, but reheating eliminates this issue. ESBO is used in PVC applications such as flooring, hoses, food packaging, and more. It is also used in adhesives, coatings, rubber manufacturing, and as a fuel additive. Additionally, ESBO finds prominence in the food and pharmaceutical industries.
