Epoxidized soybean oil/ESBO performance
Chemical formula of epoxidized soybean oil
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

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.
