Basotect Melatech melamine based acoustic foam is a unique, flexible, open-cell foam, possessing a combination of low weight, a Class 0 fire specification and good sound absorption properties.
Produced from melamine resins, melamine foam exhibits superior fire, temperature and chemical resistance. Furthermore, being halide-free, melamine foam when exposed to either naked flame or extreme heat does not emit any of the toxic by-products associated with conventional polyurethane based acoustic foams.
Melamine's low density and flexibility provide a practical material, convenient to handle, easy to cut and install, either to original equipment or on-site projects. This outstanding versatility, coupled with choice of complementary acoustic materials, e.g. damping sheets, barriers and facings, allows Melatech foam to be used in a wide range of industrial and commercial applications where superior reverberation control is required.

Specialist facings can improve LF performance
We have developed a number of specialist facings with particular foams for improved low frequency absorption, or for specific tuning, which is often required when dealing with industrial noise issues, machine enclosures and fan casings etc. We have managed to achieve 50% efficiency as low as 125Hz and 100% efficiency from 200Hz upwards.
The acoustic test data is shown but it is a good idea to discuss your requirements with our technical team.
OEM cut parts
We can also cut this foam to specific OEM Cut Parts as well as produce acoustic foam tiles of any size up to 1200x1200mm. Tiles can have straight or bevelled edges in thicknesses from 25mm to 150mm. OEM Cut Parts can easily be supplied in pre-cut kit form.

Please note This acoustic foam can tend to expand and contract due to temperature and humidity so allowances should be made if fitting to an exact space. Due to the absorption behaviour of melamine resins and the open-cell structure of the foam, the moisture content of the material changes as a function of ambient conditions. This is associated with changes in the dimensions that occur similarly in the case of wood, concrete or tiles. This behaviour must be taken into consideration during application specification. The foam should be stored for at least 3 days prior to use under the atmospheric conditions corresponding to its later use.
