Chemical resistance According to EN ISO 175, SH0051 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.

  • Use of high quality acoustic foams from Germany
  • Precision manufacturing on the latest CNC cutting machines and systems
  • Standard solutions or individual small and series manufacturing of noise insulation

„The sound absorber SH0051 MH is a further development of the known pyramid foam and because of its extremely high heat and flame resistance and chemical resistance has flexible uses. Its areas of use therefore are ideally in technical areas such as machine production, and for machine dampening or sound insulation booths. Of course, we also produce individual sound insulation form parts corresponding to the requests of our customers. In this way they get the perfect profile solution for almost every sound insulation measure.“
