ALPHARETTA, GA. - Amoco Chemical Co. has begun a two-stage expansion of polysulfone polymer production at its Marietta, Ohio, plant. The first phase will increase capacity at the plant by one-third, to about 30 million pounds per year. The second phase will increase it by the end of the year by an additional 20 percent, R.L. McNeel, vice president and general manager of Amoco Polymer Business Group, said in a company statement May 4.
Roy Duffus, a spokesman for Amoco, said the expansion is in response to growing demand for polysulfone, which is used widely in medical, home appliance, plumbing and other markets where materials are subjected to frequent sterilization or to high heat.
Duffus said polysulfone is being used more in electrical and electronics markets for electrostatic packaging of microchips, and business machines where dimensional stability and chemical and heat resistance are essential. It remains commonly used in often-sterilized medical equipment such as instruments and trays, and in plumbing applications such as faucets, flow valves and anti-scalding de-vices.
Duffus said the Marietta facility is the only Amoco plant producing polysulfone, and that the expansion will be facilitated by increases in production of the sulfone monomer at Amoco's Augusta, Ga., plant.
Amoco Polymer Business Group, based in Alpharetta, is a business unit of Amoco Chemical Co. in Chicago.
