Epoxidized Plasticizers

Epoxy plasticisers are esters containing an epoxy group such as epoxidised soybean oil (ESBO). They are formed by the epoxidation of an olefinic double bond to an oxirane structure.

Epoxidized soybean oil (ESBO) is a collection of organic compounds obtained from the epoxidation of soybean oil. It is used as a plasticizer and stabilizer in polyvinyl chloride (PVC) plastics. ESBO is a yellowish viscous liquid.

It serves as a plasticizer and a scavenger for hydrochloric acid released when the PVC degrades thermally.

Epoxidized soybean oil, ESBO or ESO, is a plasticizer which can be used in PVC products (polyvinyl chloride films, gaskets, Masterbatches, compounds, etc.), such as all kinds of food package materials, medical products, different kinds of films, sheet materials, tubing, gaskets, refrigerator sealing strips, artificial leather, plastic wallpaper, electrical wires and cables, other plastic products and for food contact applications. ESBO is also used in PVC cling films for wrapping foods and toys.
