CHEMTURA ANNOUNCES PRICE INCREASES FOR CERTAIN BROMINATED FLAME RETARDANTS, MARK® TIN PVC HEAT STABILIZERS AND EPOXIDIZED SOYBEAN OIL PVC PLASTICIZERS

In response to significant raw material cost inflation and mounting regulatory expenses, Chemtura Corporation (NYSE:CEM) will increase prices on a range of polymer additives used primarily in the Building & Construction and Consumer Products industries. Specific product lines affected are:

• Firemaster®550/552/600/602 flame retardants used in polyurethane cushioning will increase by $0.09/lb. This increase is effective globally on January 1, 2008 or as contracts allow.

• Derivatives of the flame retardant HBCD used in polystyrene, including CD-75PTM and SP-75TM, will increase by 10%. This increase is effective globally on January 1, 2008 or as contracts allow.

• Chemtura’s Drapex® epoxidized soybean oil PVC plasticizers will increase by $0.22/kg ($0.10/lb) or Euro 0.14/kg in direct response to unprecedented increases in commodity soybean oil prices. This increase is effective globally on January 1, 2008 or as contracts allow.

• Mark® tin based heat stabilizers for PVC will increase by 5% due to increases in non-tin raw materials and energy. This increase is effective globally on January 1, 2008 or as contracts allow.

• Additionally, as the cost of elemental tin continues to push $17,000/MT, an adjustment of between $0.02/lb and $0.10/lb ($0.05/kg to $0.22/kg) dependent on tin content will be made to the existing tin surcharge effective December 10, 2007.
