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. |
