Bisphenol A (BPA) is a difunctional phenolic compound produced by the condensation of acetone and phenol. The polycarbonate grade (BPA-157) is essentially 2,2-bis (p-hydroxyphenyl) propane (see formula below) with only trace amounts of other isomers.

Polycarbonate Grade Bisphenol A is a white flaked solid of high purity used as a major ingredient in high molecular weight linear polymers such as polycarbonates and polyesters.
