Application

DEGDB can be used as a plasticizer in the fabrication of carbon black composite based sensors, which are used for the detection of electronic noise systems. It may be homogenized with poly(vinyl fluoride) and polysulfone based composite to prepare an electrolyte for lithium ion batteries.

General description

Di(ethylene glycol) dibenzoate (DEGDB) is a widely used dibenzoate ester based plasticizer, which has either linkages at the center that connect the two benzoate groups.
