BPA

BPA

Bisphenol-A(BPA) is a white, solid chemical produced by recombining phenol and acetone catalyzed by hydrochloric acid. BPA also reffered to as 2,2-bis

(p-hydroxyphenyl) propane and Diphenyolpropane, has a structure which makes it suitable as a monomer to produce polycarbonate, epoxy, phenolic, polyester and other resins.

Used directly  as am additive, it improves the stability of many other resin systems. The presence of two hydroxyl groups at opposite ends of the chemicals under reasonably mild process conditions.
