Epoxidized soybean oil/ESBO
  • Chemical formula of epoxidized soybean oil/ESBO/ESO

    Molecular formula: C57H106O10
    Molecular weight: About 1000


    epoxidation of soybean oil,aAt normal temperature, is pale yellow viscous oily liquid. It will be solidified when the temperatureis lower than 5°C.ignition point: 310°C, viscosity 325mPa.s (25°C), refractive index 1.472 (25°C),watersolubility<0.01% (25°C), solubility of water in this product: 0.55% (25°C). It is soluble in hydrocarbon, ketone,esters, higher alcohols and slightly soluble in ethanol.


    ESBO is the most widely-used epoxide plasticizer and stabilizing agent of polyvinyl chloride.It has good compatibility with PVC resin. It has low volatility and little mobility. And it has great thermostability and light stability. It's water-proof and oil-proof. We can use it to make the products have good mechanical strength,resistance to elements and electrical property. What's more, it's nonpoisonous and can be used as the assistant of food package materials which has been authenticated internationally.

    Technical Specification:




    transparent light yellow oily liquid without visible impurities

    Epoxidized soybean oil/ESBO can be used in most products of polyvinyl chloride, such as all kinds of food package materials, medical products, different kinds of films, sheet materials, tubing, sealing strip of refrigerator, artificial leather,plastic wallpaper, electrical wires and cables and other commodity plastic products .It also can be used as special printing ink and liquid composite stabilizer.


    NW: 200kg. Packed in metal pail or on the clients' requirements.

    • 1.Epoxidized soybean oil/ESBO is good result, compitive price plasticizer, PVC stabilizer

      2.Epoxidized soybean oil have many applications on plastics

      3.Epoxidation of soybean oil usually used with other plasticizer and PVC stabilizer together
