## products and Markets 

<img src='content_image/194620.jpg'>

Industrial Chemicals serves a diverse group of markets, from economically- sensitive industrial sectors to technology-intensive specialty markets. We process and sell refined inorganic products that are sought by customers for their critical reactivity or specific functionality in markets such as glass, detergents, chemicals and pulp and paper. In addition, we produce, purify and market higher value downstream derivatives into specialized and customer-specific applications. These applications include electronics, biocides and animal nutrition. 

## alkali 

Our Alkali Chemicals Division produces natural soda ash. Soda ash is used by manufacturers in glass, chemical processing and detergent industries. To lesser degrees, we also produce sodium bicarbonate, caustic soda and sodium sesquicarbonate. The majority of our alkali sales are manufactured by and sold through FMC Wyoming Corporation, which we manage as an integral part of our alkali business and in which we own shares representing an 87.5 percent economic interest, with the remaining shares held by two Japanese companies. 

We mine and produce natural soda ash using proprietary, low-cost mining technologies, such as longwall and solution mining, which we believe give us the lowest cost position. Our two production sites in Green River, Wyoming have the name plate capacity to produce approximately 4.85 million tons of soda ash annually, with approximately 1.3 million tons of this capacity mothballed at December 31, 2010. During 2009, with the economic downturn resulting in a drop in soda ash demand, we mothballed the Granger facility and consolidated all of our soda ash production at the Westvaco facility. Since then, U.S. export markets have recovered much faster than the U.S. domestic market, and in January 2011 we announced the restart of our Granger production at a rate of 500,000 tons per year by July 1, 2011 to satisfy export demand. We plan to evaluate further production increases at Granger during 2011. 

## peroxygens 

We produce hydrogen peroxide at production facilities in the United States, Canada, Spain and the Netherlands. We also participate in a joint venture company in Thailand. We sell hydrogen peroxide into the pulp and paper industry, and increasingly to the chemical processing, environmental, electronics and food industries. We are a leading North 

<img src='content_image/194617.jpg'>

American producer of hydrogen peroxide due in part to our broad product line, geographically-advantaged plant locations, state-of-the- art processing technology and superior customer service. Hydrogen peroxide represents approximately 65 percent of our peroxygens sales. 

Our specialty peroxygens business supplies persulfate products primarily to polymer, printed circuit board, hair care and soil remediation markets. Peracetic acid is predominantly supplied to the food industry for biocidal applications. Typically, we compete as a specialty player where we believe that we are differentiated by our strong technical expertise, unique process technology, intellectual property and geographic location. 

## zeolites and silicates 

We have two manufacturing facilities in Spain where we have market position in zeolites and silicates. We sell zeolites and silicates products which are used in detergents, car tires, pulp and paper markets. We are exploring new applications of the zeolite and silicate uses including water treatment, environmental applications and agricultural markets. 

## industry overview 

Through December 31, 2010 we primarily participated in the following product areas: soda ash, peroxygens, phosphorus chemicals, zeolites and silicates. Subsequent to December 31, 2010 and as a result of the Huelva facility shutdown, our primary product areas are: soda ash, peroxygens, zeolites and silicates. These products are generally inorganic and are generally commodities that, in many cases, have few cost-effective substitutes. Growth is typically a function of industrial production in developed economies and a function of the rate of industrialization in developing economies in the export markets. Pricing tends to reflect the supply and demand balance as producers add or reduce capacity in response to demand changes. 

## soda ash 

Soda ash is a highly alkaline inorganic chemical essential in the production of glass and widely used in the production of chemicals, soaps and detergents, and many other products. Natural soda ash is typically produced from trona, a natural form of sodium sesquicarbonate, through mining and chemical processing. Soda ash may also be produced
