New flame retardant for flexible polyurethane foams

Great Lakes Chemical Corporation : 26 October, 2001  (New Product)
Great Lakes Chemical Corporation has introduced a new high performance flame retardant for flexible polyether and polyester polyurethane foams.
Great Lakes Chemical Corporation has introduced a new high performance flame retardant for flexible polyether and polyester polyurethane foams.

Firemaster 550 is a new, non-scorch, phosphorus-bromine flame retardant based on proprietary Great Lakes technology. This new flame retardant offers all the advantages of the long-established Great Lakes DE-60F Special without utilising brominated diphenyl ether (brominated diphenyl oxide) chemistry.

Firemaster 550 is a low viscosity liquid with good compatibility in polyurethane systems where it disperses uniformly and produces white foams with fine cell structure and good hand and physical properties. Firemaster 550 typically provides 30-50% lower compression set than other flame retardants used in polyurethane foams. Since Firemaster 550 does not cause centre softening in HR foams, it is particularly effective in CO2 blown systems.

Additionally, foams formulated with Firemaster 550 meet MVSS 302, CAL TB 117 parts A and D, as well as the more stringent UL94 HF-1 specification.
