Epoxidized Soybean Oil (ESO) is a nonpoisonous and tasteless PVC plasticizer. It maintains stability under light and heat with a molar weight of approximately 1000. It is highly effective for steady performance, volatility resistance, and lowering loss, significantly extending the useful life of PVC products.
Applications: Suitable for all kinds of PVC products (hard or soft). It enhances physical property machinability and provides essential conditions for PVC resin in packaging applications.
