Chemical resistance
According to EN ISO 175, FLAT Tec Plus 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.
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 determining the absorption values
Our aixFOAM sound absorbers have been tested for Hertz and pores in the reverberation chamber of renowned institutions. The sound absorption coefficients according to DIN EN ISO 354 (reverberation chamber) stated above were calculated in extensive measurements.
