? ESO generally refers to epoxidized soybean oil.

epoxidized soybean oil is a kind of organic matter with the chemical formula of (RC2H2OR'COO)3C3H5, which is a light yellow viscous oily liquid at room temperature. Non-toxic The boiling point is 15℃(.53 kPa). Soluble in most organic solvents and hydrocarbons, insoluble in water. Excellent heat resistance, light resistance and compatibility. It is often used as plasticizer in PVC products, especially in PVC transparent products, food packaging products and other non-toxic products.

its application:

generally, vegetable oil plasticizer has been applied to PVC resin, and the dosage is 15%. The dosage of modified vegetable oil plasticizer can be higher than 15%, 2%, 4% and 5%. The upper limit of typical plasticizer dosage is about 7%. High concentration of epoxy plasticizer will provide high thermal stability.

ESO is a non-toxic plastic plasticizer, which is approved by the US Food and Drug Administration (PDA) and can be used as a plasticizer for food packaging materials. ESO is used as a plasticizer in the production and manufacture of PVC non-toxic products, transparent PVC products, transparent bottles, transparent boxes, food and drug packaging materials, PVC medical "blood transfusion bags", PVC outdoor plastic products, waterproof coiled materials, plastic doors and windows, wallpaper plastic films, etc.
