GENERAL
DESCRIPTION
|
|
BISPHENOL-A
(BPA) is produced through an acid-catalyzed condensation
reaction of phenol with acetone. BISPHENOL-A's
(BPA) growth prospects remain bright, based
on the high growth expected for CDs during the next
few years and the emergence of new markets, such
as polycarbonates for auto-glazing, that could develop
after the turn of the century. Epoxies are projected
to grow at a more modest 3 to 4 percent annual
rate, based on continued wide acceptance in adhesives,
powder coatings, and electrical and electronic applications.
Bis-A used in flame retardants is forecast to grow
4 to 5 percent annually through the early years
of the new century. In the environmental area, recent
industry-sponsored research has found no evidence
of biological effects from low-dose exposures to BPA.
