Epoxidized soybean oil is a chemical product obtained by the oxidation treatment of soybean oil. It is a light yellow viscous oily liquid at room temperature. It is a widely used non-toxic plasticizer and stabilizer for polyvinyl chloride. The resin has good compatibility, low volatility, and low migration. It has excellent thermal stability and light stability, as well as water resistance and oil resistance. It can endow products with good mechanical strength, weather resistance, and electrical properties, and is non-toxic. It is an internationally recognized chemical process additive for food packaging materials.
nature
Epoxidized soybean oil is referred to as ESO, and its composition is linoleic acid (51%~57%), oleic acid (32%~36%), palmitic acid (2.4%~2.8%), stearic acid (4.4%~4.6%) )Wait. Light yellow oily liquid with a relative density of 0.989. Epoxy value of 6.6%. Freezing point - 8 ℃. Boiling point 150 ℃ (0.53kPa): refractive index 1.4716. Viscosity (25℃) 325mP.a·s. Flash point (open ring) 280 ℃. Soluble in alkanes and most organic solvents, slightly soluble in water. Compatible with polyvinyl chloride, chlorinated rubber, and nitrile rubber. Low volatility, low migration, excellent heat resistance, light resistance, and weather resistance. Nontoxic. biodegradable.
use
It is widely used and is often used as a non-toxic plasticizer and stabilizer in PVC products: it has good compatibility with PVC resin, low volatility and low migration.
Its flash point is high, generally above 285 ℃, it has excellent thermal stability and light stability, water resistance and oil resistance are also good, it can give products good mechanical strength, weather resistance, and electrical properties, and it is non-toxic. Approved chemical process aid for food packaging materials.
