Bisphenol A (BPA)
Bisphenol A (Polycarbonate Grade) is a difunctional phenolic compound produced by the condensation of acetone and phenol. The polycarbonate grade 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 crystalline solid of high purity used as a major ingredient in high-molecular-weight linear polymers such as polycarbonates and polyesters.
Application
Bisphenol A is primarily used in the production of epoxy and polycarbonate resins. Other uses for Bisphenol A include flame retardants, unsaturated polyester resins, polyarylate resins, polyetherimide resins and polysulfone resins.

Epichlorohydrin (ECH)
Epichlorohydrin is a colorless, mobile liquid with a characteristic chloroform-like, irritating odor. It is employed as a raw material for the manufacture of a multitude of glycerol and glycidol derivatives used as plasticizers, stabilizers, solvents, dyestuff intermediates, surface active agents and pharmaceuticals, and as intermediates for further synthesis.
