Polyphosphonate FRs for high-temperature PUR foam

FRX Polymers (a pinfa member company) has launched an innovative new grade of non-halogenated oligomeric PIN flame retardants for high temperature polyurethane flexible foams. The new grade of polyphosphonates can achieve UL94-V0 fire performance combined with high temperature resistance and dimensional stability as demanded in transport and electronics applications. Mechanical performance is maintained after ageing at 150°C enabling use in demanding applications such as motor compartment vehicle parts or noise/vibration foams, electric battery packs and electromobility electronics. The polyphosphonates are available in both powder and liquid formulation, so improving processing efficiency, and were developed to respond to automotive industry needs for a replacement for expandable graphite in one-step foam processes for engine compartments.
