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 plasticizer and stabilizer for PVC: and PVC The resin has good compatibility, low volatility and low migration. It has excellent thermal and light stability, water resistance 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.

The product is a light yellow viscous oily liquid at room temperature. The solubility in water is <0.01 (25°C), and the solubility of water in the product is 0.55% (25°C). It is soluble in hydrocarbons, ketones, esters, and high-grade organic solvents such as alcohol are slightly soluble in ethanol. This product is the most widely used PVC non-toxic plasticizer and stabilizer: it has good compatibility with PVC resin, low volatility and low migration. It has excellent thermal and light stability, water resistance 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 for all polyvinyl chloride products. Such as various food packaging materials, medical products, various films, sheets, pipes, refrigerator seals, artificial leather, floor leather, plastic wallpapers, wires and cables and other daily plastic products, etc., and can also be used for special inks, paints, coatings, etc. Synthetic rubber and liquid compound stabilizer, etc.
Generally, the higher the ESO epoxy value, the better the heat resistance, the lower the ESO iodine value, the better the compatibility with PVC, and the less likely it is to precipitate!
