Acoustics Products

  • Providing Innovative Acoustic Solutions

    FXI acoustical materials are designed to perform a number of functions including sound absorption and vibration damping. FXI low-density foam materials are ideal for sound absorption while higher-density or lower permeability materials can be excellent for sound dampening. In addition to their acoustic capabilities, all FXI foams are moldable and meet various fire ratings for different industry uses, insulation and operating temperature requirements. FXI acoustical foam solutions provide an efficient, consistent, and predictable performance simplifying installation and material handling, reducing costs of finished part production and reliable performance over-time in high-stress environments and applications.

      Extended Performance Under Environmental Pressures with Open Cell Structure and Felting

      AEROFONIC® is a reticulated felted foam. Originally designed for the highly demanding environments found in the aerospace industry. Felting is a process by which heated platens permanently compress the foam to a specified density (firmness) and thickness. By varying machine conditions and the ratio of initial foam thickness to final felt thickness, the specific design properties of the end product are controlled.

      Typical applications:
      • Aircraft air duct liner
      • Aircraft turbine engine
      • Diesel powered
      on-and off-road equipment
      • Armored vehicles
      • Air-conditioning equipment

    • Hyfonic™ Natural
      Sound Absorbing Foam using a Renewable Profile

      The Hyfonic™ Natural is a lower to medium density, combustion-modified, polyether foam developed to resist hydrolytic degradation. Being an excellent sound absorbing foam, Hyfonic™ Natural is produced utilizing natural oil polyol (non-food source). This fire retardant, flexible foam has been designed for applications where flammability must meet standards like the Department of Transportation FMVSS-302 and Underwriters Laboratory UL 94 HF-1. Hyfonic™ Natural resists degradation from hot, humid environments and has excellent stability in high and low temperatures.

      Typical applications:
      • Door and trunk panels for vehicles
      • Vibration reduction
      • Sound reduction panels for marine, agricultural
      and industrial equipment

    • PYRELL®
      Intumescent Sound Absorbing and Fire Retardant Foam
      UL 94 HF-1

      PYRELL® is a combustion modified, halogen-free, flexible polyester polyurethane foam that intumesces when a flame is applied. This means that when flame is applied, the surface chars and forms a protective shield between the flame and the foam underneath. This carbon char has low thermal conductivity and high oxidation resistance.

      Typical applications:
      • Packaging for aerospace
      • Padding
      • Insulating
      • Motor shroud
