PS
Most capacity for solid crystal and impact resins is flexible.
BASF closed two of its older, small-scale plants: Holyoke, Mass., in 1997 (80 million pounds) and Santa Ana, Calif., in 1998 (75 million pounds). BASF also added 315 million pounds of new capacity by building a plant in Altamira, Mexico, in 1997, and by expanding its Joliet, Ill., site in 1998 from 520 million pounds to 760 million pounds.
Chevron expanded its Marietta, Ohio, facility by 250 million pounds in 1997, bringing the complex's annual capacity to 800 million pounds.
In 1998, Huntsman closed its Willow Springs, Ill., facility, losing 75 million pounds, and the company reduced its capacity at Belpre, Ohio, by 80 million pounds.
In 1999, Nova bought Huntsman's polystyrene business, except for the plant in Peru, Ill.

ABS
Some production is from swing capacity, which can be used to produce either ABS or polystyrene. Almost all of the ABS produced is for the merchant market.
Last year, Bayer closed its plant in Muscatine, Iowa, removing 160 million pounds from the market, but additional capacity is expected to go into the Addyston, Ohio, plant.
Diamond Polymers' expansion to 50 million pounds was completed last year.
Dow's plant in Torrance, Calif., with a capacity of 40 million pounds, is currently running polystyrene because of market conditions.
In 1998, GE Plastics added 100 million pounds of new capacity to its site in Ottawa, Ill., while cutting capacity by 120 million pounds at Washington, W.Va.
