PYRELL®

  • Intumescent Sound Absorbing and Fire Retardant Foam 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.

      Overview

      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.

      PYRELL® has a nonmigrating flame retardant system. It retains its flame-retardant property even after aging. PYRELL® offers all of the familiar advantages of flexible polyurethane foams and is easy to fabricate. PYRELL® can be laminated to a variety of substrates including paper, vinyl, pressuresensitive tape, other foams, many plastic films, cloth and non-wovens.
