Firemaster® 550

With Firemaster® 550, Great Lakes has lead the effort to develop the next generation of cost-effective, environmentally responsive flame retardants that exceed the highest fire safety standards. Firemaster® 550 is a penta replacement. It is available in the Americas and Asia Pacific regions only.

Although the EPA has concluded that PBDEs are not a risk to the public, there is growing public concern about the persistence and bioaccumulation of penta products. Accordingly, Great Lakes has decided to work proactively with customers to transition away from Penta-PBDE in an orderly manner, years ahead of any legislatively-mandated deadlines.

Firemaster® 550 has certain commercial applications that are superior to the penta-based products it will replace. Because of its physical and chemical properties, Firemaster 550 can now be used for flame lamination in products such as automobile headliners. It can also be used as a fire retardant in insulation foam, packaging foam and acoustical foam.
