Isofon A51 is a flexible, open-cell polyurethane foam. The face sealed with an oil and water repellant viscose-polyester non-woven. Used for sound absorption, thermal insulation and vibration insolation. A pressure sensitive adhesive with release film is optional.
Isofon A51 repels water, oil, diesel,… and therefore is suitable for sound absorption and insulation in engine compartments, vehicles, boats,…
Sheets of 2000 x 1000 mm
- Thickness: 10, 20, 25, 30, 40 and 50 mm
- Specific formats and cut-outs on demand.
Isofon A51 meets the requirements of FMVSS 302.
