Sheffield Plastics Inc. has increased its polycarbonate sheet capacity with the addition of a new Breyer line in Sheffield.
The firm, a subsidiary of Bayer MaterialScience Co., said the new line has technical advances to make PC sheet with much lower visual distortion than is obtained with conventional lines. Cost and capacity figures were not disclosed, but Sheffield claims the system is the largest and most technologically advanced of its kind.
Sheffield spokesman D.J. Jantz said in a telephone interview that some of the fastest-growing PC sheet markets are national security, architectural glazing and transportation.
The company began using the new line in the middle of the second quarter.
The sheet extruder runs two plants in Sheffield and one in Berlin, Conn. It extrudes a range of engineered Makrolon sheet based on Bayer's PC resins, as well as copolyester sheet and PC blend sheets.
Plastics News estimates that the company operates 13 extrusion lines and has estimated annual sales of about $180 million.
