Description

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.[1][2]

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.[3][4] It may be homogenized with poly(vinyl fluoride) and polysulfone based composite to prepare an electrolyte for lithium ion batteries.[5]
