• Extended Performance Under Environmental Pressures UL 94 HF-1

    • FXI acoustical solutions are engineered to perform multiple functions including sound absorption and vibration damping. FXI low-density foams are ideal for sound absorption while higher-density or lower permeability foams work well for damping. Complementing their acoustic capabilities, all FXI foams are moldable and meet various fire and performance requirements. Additionally, these acoustic technologies can withstand varying operating temperatures and offer insulation performance for different industry applications. FXI acoustical solutions provide efficiency, reliability, and predictability in high-stress environments and applications over time, while simplifying handling, manufacturing and assembly, to reduce overall costs for sound and vibration reduction solutions.


      Hyfonic™ is a combustion-modified polyether polyurethane foam developed to resist hydrolytic degradation and has excellent sound absorbing characteristics. Hyfonic™ has robust high and low temperature features capable of withstanding intermittent temperatures as high as 250 °F, and at -40 °F shows no evidence of cracking or tearing when bent around a mandrel equal in diameter to the foam thickness. Hyfonic™ meets standards such as Department of Transportation FMVSS-302 and Underwriters Laboratory UL 94 HF-1.
