Epoxidized soybean oil and DOP are an oil used by many customers. Epoxidized soybean oil is a widely used non-toxic and odorless plasticizer and stabilizer for polyvinyl chloride and neoprene. Good stability, good compatibility, low volatility and low mobility, it can not only absorb the hydrogen chloride released from the decomposition of polyvinyl chloride resin, but also be miscible with polyvinyl chloride, which can improve the physical properties of polyvinyl chloride products. Extend product life. DOP dioctyl phthalate belongs to phthalate plasticizer and is widely used.
Then let's take a look at the difference between the two:
1. Appearance, epoxidized soybean oil: light yellow oily liquid; DOP: colorless oily liquid.
2. Polar group, the polar group of epoxidized soybean oil is epoxy group, and that of DOP is ester group.
3. Chemical structure, epoxidized soybean oil is an epoxy compound, and DOP is a phthalate ester.
4. Main properties and applications: Epoxidized soybean oil is used in PVC non-toxic products, transparent products, pellets, transparent bottle caps, food, drug packaging materials, PVC medical products, blood transfusion bags, patch paper, waterproof Coils, plastic films, etc., can ensure that the products are non-toxic, transparent, have excellent light and thermal stability, and prolong the service life of the products. DOP has good compatibility and plasticizing effect, and has relatively comprehensive performance. It is often used as the main plasticizer. However, due to its high volatility and poor durability, DOP can be well mixed with polyvinyl chloride (PVC) resin. It has good electrical properties, good low temperature properties, low volatility, relatively low extraction and toxicity, and many other advantages, so it can be satisfactorily used in various formulations, such as cables, films, etc.
Epoxidized soybean oil has good flame resistance, weather resistance, low volatility, small migration, and good compatibility with PVC. Pay attention to heat-resistant wires and agricultural films.
