SHANGHAI (April 17, 2007) -- Russia’s KuibyshevAzot Joint Stock Co. plans to grab market share in China’s market for nylon 6 compounds through its new Shanghai joint venture KuibyshevAzot Engineering (Shanghai) Co. Ltd.
“We can be very competitive in the China market because of the lower price of feedstock in Russia,” said General Manager Roman A. Meytis.
KuibyshevAzot, based in Russia’s Samara region, inaugurated the 4,200 square meter plant at the end of March. The facility is a joint venture with He Ye Trading Co. Ltd. of Shanghai. The two companies have been business partners for 20 years. KuibyshevAzot is the controlling shareholder of the facility, which is located in the Qingpu Industrial Park near Shanghai.
KuibyshevAzot Shanghai plans to acquire 7,000 metric tons per year of the nylon 6 resin from its parent in Russia to produce other engineering compounds. The company’s main product is a glass-fiber-reinforced nylon with a flame retardant additive. But the joint venture can also produce polyethylene, polypropylene and other compounds.
With two extrusion lines currently working, the facility can produce 9,900 metric tons per year, and plans to expand to a total of four extrusion lines over the next 24 months. Germany’s Berstorff GmbH provided the extrusion machinery.
KuibyshevAzot hopes to develop long-term relationships with customers. “We can control quality, quantity and price,” Meytis said.
He added that the company’s compounding joint venture in Moscow, with Moscow-based Polyplastic Group, has given KuibyshevAzot experience in serving automotive and electric appliance customers, which are two of China’s fastest growing users of engineering plastics.
KuibyshevAzot employs more than 5,000 and produces ammonia, nitrogenous fertilizer, caprolactam and nylon at its 3,000,000-square-meter facility in the Samsara region of Russia, near Moscow.

[+/-] : Washington State Establishes Flame Retardant Review Process
Initiates process to search for “alternative” to proven flame retardant known as Deca
Washington, D.C. – The State of Washington today established a formal, three-step process for identifying and approving “alternative” flame retardants that could come into use in Washington.
“As several state Senators and Representatives said repeatedly during the legislative process, this is not a ban, but a bill that establishes a process under which three separate entities have to identify, evaluate and approve any ‘alternative’ flame retardant that is proposed to replace Deca in Washington,” said Dr. Michael Spiegelstein, chairman of the Bromine Science and Environmental Forum (BSEF), an industry trade association.
Under the bill, the Departments of Ecology and Health, as well as a newly-created fire safety committee, would have to determine that any proposed alternative flame retardant is “safer and technically feasible” as a replacement for the well-known Deca product, which is primarily used in plastics and some commercial textiles to provide flame resistance. The use of Deca in certain consumer products would not be prohibited unless and until such an alternative is approved.
The bill does place a prohibition on the use of Deca in mattresses beginning Jan 1, 2008, but since Deca is not actually used in residential mattresses, that prohibition has no practical impact.
“It is unfortunate that the Governor signed this legislation, since Deca is highly effective and the most studied flame retardant on the market, and we remain concerned that the review process is somewhat vague and ill-defined,” Spiegelstein said. “But we will nonetheless continue our efforts in Washington to ensure that this safe, life-saving product is evaluated fairly and to make sure the state agencies follow the process faithfully, openly and objectively.”
Noting that the European Union undertook a 10-year-long risk assessment of Deca and then exempted it from further regulation, Spiegelstein said he is confident that a fair and objective analysis of Deca and proposed alternatives will show that Deca is an effective product that is safe for use.
The difficulty of properly evaluating and approving alternative flame retardants was highlighted recently when the Washington Department of Ecology and several local environmental organizations began openly endorsing the substance melamine as a “safer” replacement for Deca, only to have it revealed a short time later that melamine is the contaminant in pet food that led to numerous pet deaths across the country.
“The use of safe, effective flame retardants saves many lives every year by preventing or slowing down fires,” Spiegelstein said. “The real risk in Washington is that the substitution of one product for another is not as simple as some people think – any substance used as an alternative to Deca will carry its own risks, and we may not even be aware just what those risks are because no alternative has been studied as extensively as Deca.”
Spiegelstein also noted with irony that the legislation passed in Washington contains so many exemptions and loopholes for current Deca applications that, in practice, it would only address a small portion of actual Deca use in the state.
“This legislation was carefully crafted to eliminate opposition by providing exemptions to every major user of the product in the state,” he noted. “It should be clear to the people of Washington that this bill is much more about achieving a political victory than about good science and ensuring fire safety.”

[+/-] : Flame retardant raises health concerns
Minnesota lawmakers are considering banning something you may have never heard of, but probably have in your home. It's a flame retardant commonly found in electronics and furniture.
Supporters of the ban say the chemicals are toxic, and closely related to chemicals already banned in the European Union and California. Manufacturers say flame retardants save lives, and there aren't good substitutes.
St. Paul, Minn. — At the Minnesota state Capitol on a recent afternoon, environmentalists were zapping TV sets, computers and furniture with an analyzer gun.
A Toshiba television set in the Secretary of State's office gave them what they were looking for: 14 percent bromine.
Bromine has been widely used in flame retardants since the 1970s, in everything from TV sets to upholstery backing. But recently some scientists have become concerned.
They're investigating the flame retardant's potential links to cancer, developmental problems in children's brains and interference with the immune system.
"There was so much data for their universal occurrence in the environment -- in sediment, sand and soil, in wildlife and people -- that it was just a real awakening."
- Linda Birnbaum, Environmental Protection Agency
Kathleen Schuler of the Institute on Agriculture and Trade Policy, the environmental group with the analyzer, wants to find other ways to protect people from fires. "We're not saying that it's going to make them sick, or that it's necessarily going to create an unhealthy environment," she said. "What we're talking about is putting toxic substances in objects when we know there are safer alternatives."
Schuler's group pushed for a ban on brominated flame retardants in Minnesota three years ago. At that time, California banned two brominated flame retardants. The main manufacturer, Great Lakes Chemicals, voluntarily ceased production.
But the most common brominated flame retardant, known as "deca," is still widely used.
Deca prevents things like TVs from catching on fire and stops fires from spreading. Flame retardant makers say their products save hundreds of lives a year.
Steve Maki, vice president for technology at RTP, a Winona company, drove to the State Capitol twice this year to testify against the proposed ban. His company makes the plastic that ends up in things like light switches and electrical connectors.
"One of our biggest applications would be timer components that go into washing machines or dryers," he said. "Sometimes when you hear the washing machine and turn the dial to set the cycle on your washing machine, they need to pass a certain flammability requirement."
To keep that plastic from burning, RTP mixes in deca. Maki brings out a small vial that looks like powdered sugar.
"We handle this material in its raw form, which is the exact powder," he said. "We've been using it for 25 years here at RTP. We use lots of it, and we've never had a single incident with health or environmental concern with this additive."
In its lab in Winona, RTP does flame tests on its products. Engineers reach into a compartment that looks like a big oven with a sliding door, and use Bunsen burners to try to light things on fire.
In this test, one piece of plastic that looks like a white popsicle stick has deca in it. The other one, a clear stick of plastic, doesn't.
The deca-treated stick stops burning as soon as the burner is pulled away. The blackened plastic smokes then snuffs out.
"You saw how quickly -- it was probably a second or so that fire goes out," Maki said.
But the plastic with no flame retardant curls like melted wax.
"The whole bar is engulfed in flame right now. There's dripping particles of polypropelene igniting whatever source is below," he said. "This bar is going to burn all the way up. There isn't going to be anything else. If you had a component made with this type, it would totally consume itself."
Maki said RTP does work with alternatives to deca, but it doesn't find them as effective, especially in the plastic used to make switches, battery casings and things like that washing machine dial.
Maki said about 10 years ago, his company started tracking developments in Europe, where scientists first began raising concerns about brominated flame retardants.
A Swedish researcher found the chemicals showing up in human breast milk. That set off a flurry of international research to see where else they might turn up. "I felt like I had been hit by a speeding train," said Linda Birnbaum, the director of the experimental toxicology division at the U.S. Environmental Protection Agency. Birnbaum said by 2001, all the new data about flame retardants was unsettling.
"Not only were they associated with a multitude of effects in animal studies, but there was so much data for their universal occurrence in the environment -- not only in sediment, sand and soil, but in wildlife and people -- that it was just a real awakening," she said.
The flame retardants have three traits scientists like Birnbaum worry about -- they are persistent, they accumulate in living creatures and they are toxic.
"There's clear evidence for deca in fish, birds, marine mammals, polar bears, also in people." she said.
Birnbaum said North Americans have levels of flame retardants in their bodies approximately 10 times higher than Europeans or Japanese, and they are doubling every two to five years. Those levels include flame retardants that have been phased out but are still circulating in the environment.
But it's not clear what that means. EPA official policy says there is insufficient information currently available to determine that deca presents an unreasonable risk to human health or the environment.
Since 2001, bromine manufacturers have participated in a voluntary program with the EPA to monitor possible effects of flame retardants on children.
"I think it would be fair to say U.S. EPA is all over this subject," said John Kyte, the North American policy director for the Bromine Science and Environmental Forum, an industry group.
He said given the EPA's attention, there's no reason for states like Minnesota to ban the chemicals.
"The fact that the U.S. EPA has literally dozens of programs looking at deca, ongoing analysis, checking from every possible perspective, suggests to me that these activities at the state level are unnecessary -- and could actually lead to an inconsistent patchwork of legislation that causes more problems than it solves," he said. No state has banned deca, but nine are considering it.
Europe has been the biggest battleground for chemical regulation, and that's put some pressure on global manufacturers to find alternatives.
Mark Rossi, research director from Clean Production Action in Massachusetts, flew in to meet with Minnesota lawmakers. He said big companies like Sony, Philips and Panasonic are moving away from using deca, but legislation would ensure every manufacturer does.
"We're seeing the shift happen in TV manufacturers," he said. "Where some of them have said Europe is getting out of this chemical, we're getting out of this chemical. Now in the U.S., 57 percent are deca free. Companies are making these decisions, deca free and bromine free, by 2010."
Rossi said there's no perfectly safe replacement for deca, but there are improvements. The ideal, he says, is to make products with naturally flame resistant materials so extra chemicals aren't necessary.
The Minnesota Professional Firefighters say they would support the ban.
A coalition of other fire safety groups, including the Minnesota State Fire Chiefs Association, opposes the ban, but supports a study of deca.

Magnesium hydroxide is a non-halogen flame retardant recommended where use of halogenated products is limited or prohibited. In addition, it is an excellent smoke suppressant and acid scavenger. Its high thermal stability –up to 340oC-enables its use where Aluminum trihydrate is not sufficiently stable.
It is used as a flame retardant and smoke suppressant in cables,LD and HDPE, PP homoand copolymers and nylons. It is employed as a smoke suppressant in PVC.
It is available in several surface-treated grades which are suited to specific applications.

[+/-] : Fire Retardants: An Advantageous Solution to Fire Protection
The Flammability of Fabrics
All fabrics will burn but some are more combustible than others. Untreated natural fibers such as cotton, linen and silk burn more readily than wool, which is more difficult to ignite and burns with a low flame velocity.
The weight and weave of the fabric will affect how easily the material will ignite and burn. Recommended fabrics are materials with a tight weave. Heavy, tight weave fabrics will burn more slowly than loose weave, light fabrics of the same material. The surface texture of the fabric also affects flammability. Fabrics with long, loose, fluffy pile or "brushed" nap will ignite more readily than fabrics with a hard, tight surface, and in some cases will result in flames flashing across the fabric surface.
Most synthetic fabrics, such as nylon, acrylic or polyester resist ignition. However, once ignited, the fabrics melt. This hot, sticky, melted substance causes localized and extremely severe burns. When natural and synthetic fibers are blended, the hazard may increase because the combination of high rate of burning and fabric melting usually will result in serious burns. In some cases, the hazard may be greater than that of either fabric individually.
Curtains, draperies and other articles in the home can have their burning rates reduced with flame retardants applied through chemical treatment. Such flame-retardant treatment after manufacturing is not recommended for clothing.
In terms of flammability, silk may be the worst with a high burning rate, which may be increased by the dyes and other additives to provide color.
Cotton and linen also have a high burning rate but this can be alleviated by the application of flame-retardant chemical additives.
Acetate and triacetate are as flammable or slightly less flammable than cotton. However, they can be made flame-retardant with chemical treatment.
Nylon, polyester and acrylic tend to be slow to ignite but once ignited, severe melting and dripping occurs.
Wool is comparatively flame-retardant. If ignited, it usually has a low burning rate and may self-extinguish.
Glass fibers and moacrylic are almost flame-resistant. These synthetic fibers are designed and manufactured to possess flame-retardant properties.
What is a Fire Retardant
People unfamiliar with fire retardants are surprised to hear that wood or fabric can qualify as a non-combustible material to a certain degree. Should a fire strike, the chemicals react with combustible gases and tars normally generated by the material. The tars are converted to carbon char which forms on the surface, slowing the burning rate . The combustible gases are rendered nonflammable for the most part due to dilution with harmless carbon dioxide and water vapor released in the reaction. This happens automatically, driven by the heat of the fire, and requires no coating maintenance, batteries, or plumbing; it is true passive protection.
According to the NFPA's National Fire Safety Survey findings: Although the U.S. has a higher fire death rate than Canada, Western Europe and the Pacific Rim, the majority of Americans are very confident about their fire safety. Older adults express the greatest confidence even though they have the greatest risk of fire death. Men are more confident about fire safety than women; although, of the two groups, men are at a higher risk of fire death. The majority of Americans feel safest from fire in their homes, when in truth, home fires account for roughly 80% of all fires - and they pose the greatest threat to life. The cost of operating public fire prevention services in the U.S. costs the taxpayers billions of dollars per year, most of which is spent on suppression of fire. Many people have the attitude that "fire only happens to other people." But until fire strikes their home and family, fire prevention is ignored. Once fire prevention week comes and goes each October, little thought is given to fire safety and prevention until next year's campaign. Fire suppression is a necessary and vitally important service. It is, however, "after-the-fact". This includes smoke detectors, alarms, sprinklers and extinguishers. The use of fire retardants or firestops are logical "before-the-fact" steps that should be taken. Fire spreads 1100% in the first 4 minutes. Heat rises at 90 feet per second or approximately 60 mph. Approximately 90% of fire fatalities are in the home and 90% of the fatalities occur during the sleeping hours 10pm to 6am. Remember, smoke alarms and sprinklers cannot prevent the fire, but fire retardants in most cases can prevent and/or slow the spread of fire, which can greatly prevent lose of life and property in addition to using smoke alarms or sprinklers. By applying fire retardants to your curtains, furniture, carpeting, etc., is very easy and is an added safety precaution for smokers and small children in the home. Your home and family deserve the best fire protection possible, so why not invest in it.
