MOUNT OLIVE, N.J. - BASF Corp. of Mount Olive said June 29 it will spend $60 million to build a production facility at Altamira, Mexico, to produce 315 million pounds of polystyrene per year by the middle of 1997. BASF said the plant is the cornerstone of its intentions to nearly double its PS production capacity in North America by 2000. BASF now produces 680 million pounds of PS a year at plants in Joliet, Ill., Holyoke, Mass., and Santa Ana, Calif.
BASF intends to have North American capacity to produce nearly 1.2 billion pounds of PS a year by 2000, and spokeswoman Liane Kranhold said the company is considering whether to expand production at existing facilities or to build another facility to gain additional North American production capacity.
Worldwide, BASF produces more than 2 billion pounds of crystalline, high-impact and engineering specialty grades of PS per year.
DuPont China mulls building resins plant
BEIJING - DuPont China Holding Co. Ltd. of Beijing announced July 5 it is considering building a 99 million pound-a-year polymerization plant to make acetal homopolymer resins in China.
DuPont China said it is launching a feasibility study with the China National New Chemical Corp. and the Shanghai Pacific Chemical Group Corp. Coking and Chemical Plant General to consider building the plant to produce Delrin acetal resins for markets in China, Japan, Korea and Singapore.
The three companies would be partners in the new venture, with Shanghai Pacific supplying fuel and raw materials, China National supplying its research, production and marketing strengths, and DuPont China supplying its technological strengths. DuPont's partners both are located in Shanghai.
DuPont said it and its partners could spend more than $100 million to build the plant by 1999 if the study proves positive.
One aspect of the feasibility study is to identify a location for the proposed facility.
DuPont China now is building a compounding plant for acetal resins in Shenzhen, China. That plant is to be in production by the end of this year, using imported neat resins.
The polymerization plant under study could supply neat acetal resins to the Shenzhen compounding plant.
Plasticizer exhibits carcinogenic effects
RESEARCH TRIANGLE PARK, N.C. - A study approved by the National Toxicology Program Peer Review Committee showed that a widely used plasticizer produced carcinogenic effects in laboratory rats.
The two-year feed study of butyl benzyl phthlate indicated that there was some evidence of carcinogenic activity in male rats and equivocal results in female rats.
The main use of the chemical is in sheet vinyl flooring as a plasticizing agent. It also is widely used in food packaging materials, vinyl foams and carpet materials.
The study found an incident of mononuclear leukemia in the laboratory animals in a two-year test period.
Neither the Occupational Safety and Health Administration, nor the American Conference of Governmental Hygienists has established workplace exposure limits for BBP, and the FDA has classified the chemical as a migratory, indirect food additive. NTP is in Research Triangle Park.
