Manfred Doering, Fraunhofer LBF, presented an innovative proposed solution to enable effective non-halogenated flame retardancy of expanded polystyrene foams.

Current PIN FR solutions (such as melamine, sulphur S8, phosphorus compounds) do not prevent flammability in the SBI corner test (chimney effect) and do not prevent melt-drip. The proposed technology, now available as XFLAM, coats the expanded foam beads in inorganic PIN flame retardant (water borne resin solution) before pressing into foam panels. The resulting panels offer improved mechanical and insulating properties, and can be recycled by mechanical milling.
