ESO (Epoxidized Soybean Oil) - CAS No 8013-07-8
Epoxidized Soybean Oil (ESO) is a non-poisonous and tasteless PVC plasticizer. It maintains exceptional stability under light and heat. With a molar weight of approximately 1000—significantly higher than other plasticizers—it offers superior volatility resistance and extends the service life of PVC products.
It is suitable for both hard and soft PVC applications, enhancing physical property machinability and enabling PVC resin use in food packaging areas.
