USA: DuPont Sets Up Dedicated Sorona Plant
DuPont recently dedicated the world's first continuous polymerisation plant for making the new DuPont Sorona™ 3GT polymer at its site in Kinston, North Carolina. The facility was built in response to demand for the polymer. In contrast to "batch-fed" manufacturing, continuous polymerisation is a round-the-clock process that requires feeding in precisely measured ingredients to produce uniform, consistent polymer. The 1,3 propanediol (PDO) used as a key ingredient in Sorona is currently made using a petroleum-based process. However, DuPont is developing a biotechnology process using sugar from corn and other crops as the raw material for PDO.
