Following is the molecular structure of DIOCTYL MALEATE (2915-53-9):



1.DIOCTYL MALEATE (2915-53-9) used as a bitter two sodium succinate (Fast penetrant T) intermediates. This product can also be used in plasticizers, with vinyl chloride, vinyl acetate, styrene and acrylic acid ester copolymer, the resulting copolymer has excellent impact resistance, anti-cracking properties, electrical properties and optical properties of can be used for films, coatings, adhesives, rubber, paint fixing agents, oil additives, paper-handling agent aspects. With vinyl acetate copolymer rubber for the elastic tilting can be used as paint use. Made with the vinyl chloride copolymer film has a good low-temperature softening agent. However, the proportion of goods in the copolymer should not be too large, generally less than 10%. Is too large, the copolymer resin, heat resistance and mechanical properties will decline.
2.Within its copolymers can be used as plasticizers, but also can be used as adhesives, oil additives, etc.
