Product data

Format, surface Rectangular panel (100 cm x 50 cm), nubbed profile
Material thicknesses 3 cm (1.5 cm base/ 1.5 cm nub), 4 cm (2 cm base/ 2 cm nub), 6 cm (3 cm base/ 3 cm nub)
Special sizes Cuts, punched parts, special sizes possible upon request
Material Duromer acoustic foam
Colours Dark grey
Fire classes DIN 4102 B1 (except with heavy foil lamination)
More information about the fire classes of our sound absorbers is available the relevant aixFOAM knowledge article (German).
Fastening options Without, self-adhesive kit, assembly/ hanging cassette without accessories
Lamination options Laminated with heavy acoustic foil for even more effective insulation of structure-borne sound and sound absorption in the low frequency range
Note: As a result of the laminating, the sound absorber has the self-adhesive kit as standard with an acrylic-based adhesive system. The product should only be stuck to smooth surfaces (e.g. steel, aluminium, etc.). On rough bases, the adhesive effect is limited and the self-adhesive kit should only be used as an installation aid.
Temperature­resistance - 200 °C to + 200 °C (+100 °C with heavy acoustic foil lamination)
Thermal conductivity 0,032 – 0,038 W/mK
UV-resistance Maximum UV resistance, does not yellow
Chemical resistance According to EN ISO 175, SH0021 MH as a Duromer material is resistant against many media, e.g. all organic solvents. This list of all chemical media is included in the accompanying datasheet.
Harmful substance information Certified according to Eco-Tex Standard 100 as not harmful to health, mineral-fibre free, CFC-free, propellant-free, made without using halogen-containing hydrocarbons, subject to a mandatory label according to EU directives / GefStoffV.
Tolerance This high quality acoustic product is made on our precision machinery according to DIN 7715 Part 5 P3.
In the production (foaming) of this acoustic material different sized pores (voids) can arise. Voids are typical for the material, do not represent a quality defect and do not affect the acoustic properties of the absorber.

More information about this product is available, if required, in the accompanying datasheet. We are happy to provide you with this upon request.

Absorption values

The measurements of the sound absorption coefficient were determined according to DIN EN ISO 354 (reverberation room) and refer to an absorber area of 100 cm x 50 cm.

Sound absorber/ sound insulation in the reverberation chamber when calculating the absorption coefficients
Our aixFOAM sound absorbers have been tested for Hertz and pores in the reverberation chamber of renowned institutions such as RWTH University or the Technical University in Aachen. The sound absorption coefficients according to DIN 52212 stated above were calculated in extensive measurements.

Profit from sound insulation directly from the manufacturer!

At aixFOAM we make sound insulation for applications in room acoustics and technical acoustics. And because we do this particularly well, we have been doing it for 60 years. Over this time we have been constantly working on the further development of our products and therefore are able to offer you highly effective sound absorbers in a modern design.

Our aixFOAM philosophy: We combine customer-oriented advice with the individual, needs-based production of sound insulation solutions. Or in other words: We help you with free advice to find the ideal sound insulation for your project and start to make your absorbers directly after receiving your order. You then receive your sound insulation directly from the factory – naturally in the best quality.

„SH0021 MH combines the popular, classic look of nubbed foam with high heat and flame resistance and resistance against numerous liquids and chemicals. The nubbed foam can be worked extremely easily and above all is used in machine sound insulation, in soundproofing in shipbuilding and vehicle production, as well as in cogeneration plants and heat pumps. As a result of the lamination with heavy acoustic foil, material vibrations can also be dampened.“
