Chemtura Corp. has improved versions of its Firemaster flame retardants for flexible poly¼urethane foams.
Firemaster 600 and 602 are about 10 percent more efficient than the 550 and 552 versions, according to the Middlebury, Conn., firm. They show high scorch resistance, produce minimal effect on processing, properties and cigarette smolder values, and have a good environmental profile.
Chemtura says it specifically recommends Firemaster 602 for mechanically cooled foams.
