Temperature­resistance PUR: - 40 °C to + 100 °C
Duromer: - 200 °C to + 200 °C
UV-resistance PUR: UV protection against yellowing thanks to UV blocker additive
Duromer: Maximum UV resistance, does not yellow
For further information, please refer to our matching aixFOAM knowledge article (German) on the topic of "Light ageing - UV yellowing protection"
Harmful substance information PUR: Mineral fibre free, CFC-free
Duromer: Certified according to Eco-Tex Standard 100 as not harmful to health, mineral-fibre free, CFC-free, propellant-free
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.

For those who expect more - aixFOAM Premium sound absorbers

Our sound absorbers made of thermoset acoustic foam are the ideal solution for rooms with particularly high soundproofing and fire protection requirements. They owe their unsurpassed acoustic properties to the extremely fine, open pore structure that almost completely absorbs sound. They are flame retardant without the addition of flame retardants and thus meet many regulations to ensure fire safety in public buildings.

Schallabsorber/ Schallschutz im Hallraum bei der Ermittlung der Absorptionswerte
  • Maximum sound absorption
  • Flame retardant according to DIN 4102 B1
  • Form-stable and colour-fast – no yellowing!
  • Very low weight
  • Antistatic, fibre-free and elastic

Absorption values Duromer-absorbers

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

„SH004 is characterised by a broad absorption spectrum and by its varied installation possibilities. The square absorbers can be installed creatively, for example in a chessboard pattern, as full wall or ceiling covering or as a kit system in a hanging cassette. In any case the result can be heard and seen. Because of the rounded edges, the sound absorbers can also be installed without shadow joints.“
