Replacing homes and cars in the mostly rural areas devastated by the quake and tsunami will boost Japan's demand for petrochemicals ranging from butadiene, which is used in making molded plastic auto body components, to solvents and plastics used in the construction trades.
Prices for natural rubber have stabilized at high levels but prices for synthetic rubber are increasing rapidly, driven by higher prices of butadiene, which is used to make it, Mr. Setzer said on the sidelines of the Frankfurt Motor Show Wednesday.
Now, we're also getting word here from the Kentucky division of emergency management that that chemical is something called butadiene, this is a colorless, flammable gas, mainly used to manufacture rubber and paint and that is the word coming to us from the Kentucky division of emergency management.
Some chemicals, such as butadiene, are classified as known carcinogens by the federal government.
Although the knock-off looked just like the original and had PC/PBT markings imprinted on it, materials testing revealed that it was actually made of acrylonitrile butadiene styrene (ABS) plastic, which is more brittle and not up to the job.
Operating profit in the petrochemicals segment rose 22%, backed by stable demand for polyvinyl chloride products from emerging markets such as India and the Middle East and rising prices of acrylonitrile butadiene styrene and other premium products, it said.
HOUSTON — The Environmental Protection Agency moved Tuesday to end a long-running dispute with Texas over how the state regulates emissions, including cancer-causing toxins such as benzene and butadiene, from dozens of refineries that produce a third of the nation's gasoline and billions of dollars of petrochemicals.
In 2003, Louisville Mayor Jerry Abramson had summoned representatives of three Rubbertown plants that emitted butadiene to his office, and the companies — American Synthetic Rubber, Zeon and Rohm and Haas — soon announced they would voluntarily reduce their emissions.
Within 10 days, the city released Sciences International's official draft report confirming butadiene as a problem, as well as a variety of other chemicals in the air.
American Synthetic Rubber, which had been the city's largest industrial source of butadiene, has spent about $5 million on new pollution controls, including a super-efficient burner that helped lower its emissions of the chemical from 150,000 pounds in 2000 to about 7,000 pounds last year.
