Whisper FR is a non-crosslinked closed-cell polyethylene foam, whose quite big cells have been opened during the production process. The effect of this process is a lightweight material with perfect sound absorption properties. The foam is approved fire resistant and has been tested for usability for various purposes in transportation, public transport, car and equipment production, electronics and building construction. Owing to its mechanical strength, the Whisper FR laminated foam can be installed in the form of self-bearing panels.
