What is epoxidized soybean oil?

Editor:admin │ Release Time:2018-08-17 

Epoxidized soybean oil is a chemical product made from soybean oil after oxidation treatment. It is a light yellow viscous oily liquid at room temperature. It is a widely used non-toxic polyvinyl chloride plasticizer and stabilizer: with PVC resin. Good compatibility, low volatility and small migration. It has excellent thermal stability and light stability, and also has good water and oil resistance. It can give products good mechanical strength, weather resistance and electrical properties, and is non-toxic. It is an internationally recognized chemical process aid for food packaging materials. .


This product is a light yellow viscous oily liquid at room temperature. Its solubility in water is <0.01 (25 ° C). The solubility of water in this product is 0.55% (25 ° C). Organic solvents such as alcohol, slightly soluble in ethanol. This product is one of the most widely used non-toxic plasticizers and stabilizers of polyvinyl chloride: good compatibility with PVC resins, low volatility, and small migration. It has excellent thermal stability and light stability, and also has good water and oil resistance. It can give products good mechanical strength, weather resistance and electrical properties, and is non-toxic. It is an internationally recognized chemical process aid for food packaging materials. . This product can be used in all polyvinyl chloride products. Such as various food packaging materials, medical products, various films, sheets, pipes, refrigerator seals, artificial leather, floor leather, plastic wallpaper, wires and cables and other daily plastic products, etc., can also be used for special inks, paints, coatings, Synthetic rubber and liquid compound stabilizer.


In general, the higher the ESO epoxy value, the better the heat resistance, the lower the ESO iodine value and the better the compatibility of PVC, the less likely it is to precipitate out!
