Great Lakes Further Expands Range of Flame Retardants for Flexible Polyurethane Foam
Great Lakes Chemical Corporation launched Firemaster® 552, a new high performance flame retardant for mechanically cooled, flexible polyurethane foams, at the Polyurethane Expo 2003 (Booth 511) held in Orlando, Florida on October 1-3, 2003.
Firemaster 552, a phosphorus-bromine flame retardant based on proprietary Great Lakes technology, offers the advantages of the long-established Great Lakes DE-62(TM) flame retardant, such characteristics as superior resistance to foam discoloration and smoldering ignition, reduced effect on the physical properties of the foam, and excellent hydrolytic stability. However, Firemaster 552 is not based on brominated diphenyl ether (BDE) chemistry.
Firemaster 552 has been designed to improve processing efficiency by preventing the polymer degradation caused by mechanical air cooling of flexible polyurethane foam, thereby reducing product waste. Firemaster 552 is the latest addition to the Great Lakes Firemaster® 550 family, a range of phosphorus-bromine flame retardants for flexible polyurethane foam that helps foam maintain key physical properties during processing and does not promote foam discoloration (scorch).
In addition, polyurethane foams formulated with Firemaster 552 allow foam producers to meet strict fire safety standards for automotive, furniture, bedding, and wide selection of other foam applications.
