Epoxidized Soya Bean Oil CAS 8013-07-8

Epoxidized soybean oil is an epoxy plasticizer, which is a plasticizer and stabilizer widely used in plastic processing. In the processing of industrial polyvinyl chloride (PVC) resin, it can not only absorb the HCl generated when the PVC resin decomposes, block the continuous decomposition of PVC, but also capture the free radical Cl? The free radical reaction can stabilize the active chlorine atoms on the PVC chain, slow down the degradation rate, play a stabilizing role, and prolong the service life of PVC products. If it works synergistically with metal stabilizers, its stabilizing effect is more significant.

At the same time, epoxidized soybean oil has excellent compatibility with PVC, and can be quickly and uniformly dispersed in the PVC system, weakening the force between PVC macromolecules, increasing the mobility between molecules, and improving the fluidity of PVC. It has a plasticizing effect on PVC resin. In addition, in the process of PVC processing and molding, as long as a small amount of epoxidized soybean oil is added, the operating conditions will be improved, the processing speed will be increased, the energy consumption will be reduced, the surface quality of the PVC products will be improved, and the physical properties of the products will be improved to varying degrees. , such as heat aging resistance, folding resistance, etc., play a positive role in reducing production costs and improving economic benefits. Because epoxidized soybean oil has good light and thermal stability, as well as plasticization, extraction resistance, low migration, low volatility, good compatibility, low temperature flexibility, etc., it is suitable for almost all soft and hard PVC products. Among them, such as various films, pipes, sheets, artificial leather, floor leather, wire and cable materials, refrigerator sealing strips, plastic wallpapers, gaskets, and other daily-use plastic products, photographic films with high production requirements, etc. For PVC products used outdoors, in order to ensure non-toxic, transparent, heat-resistant, low-temperature resistance, toughening, and anti-aging properties, epoxidized soybean oil must be used. Generally, adding 2-10 parts of epoxidized soybean oil to PVC products can greatly improve its weather resistance and its stability.

Epoxidized soybean oil, as an environmentally friendly, plasticized, stable and biodegradable plasticizer, fully complies with the US FDA food additive rules and EU RoHS environmental protection directives and REACH regulations. It is an internationally recognized environmentally friendly green plasticizer and is widely used in food. , pharmaceutical packaging materials, children’s toys, home decoration materials, PVC soft products, as well as transparent bottles, transparent boxes and other fields. In addition, the application of epoxidized soybean oil in coatings and adhesives is becoming more and more extensive. Because of its low price, strong photosensitivity, good film performance, good molecular chain flexibility, and low viscosity, it has three hot spots in coating applications: reaction with acrylic acid to prepare epoxy soybean oil acrylate system coatings, cationic light Curing system coatings, or mixing it into some commonly used coating systems as modifiers, such as adding epoxidized soybean oil as a reactive diluent in low VOC alkyd coatings.
