Microfilaments : a new generation of acoustic absorption material
While up to now thick and heavy materials have been used, Evolon®’s microfilament structure provides very efficient sound absorption, with a minimum thickness and a weight reduced by 10 to 30 times. It can be used as a composite under-layer, or converted to acoustic drapes, blinds and curtains.
Key Benefits
Acoustics
Evolon® has very good sound absorption properties.
The
tightly entangled multi-directional microfilaments create millions of
“micro”- air channels which allows for the optimum air permeability
required to absorb sound energy.
Environmentally-friendly
Evolon® is a long-lasting material which helps reducing the impact of waste on our environment.
In Evolon®, there is no binder, no solvent. Skin contact irritations are prevented.

Thermal insulation
Thanks to the air contained in the microfilament structure, Evolon® provides very good thermal insulation.
Standard converting
Evolon® can be processed with the traditional textile processes. It can
be dyed, printed, finished. It can also be cut and sewn as other
fabrics.
With non fraying edges, Evolon® also provides the advantage of easier converting, making overstitching useless.
As an example…
Installing Evolon® acoustic drapes in a large open-space restaurant helped reduce sound levels by 6-10 decibels
Technical Data
| Sound energy is absorbed by Evolon® thanks to the air permeability of the internal structure of tightly entangled microfilaments, with only 100g/m² and a thickness of about 0.5mm. |
Acoustics properties of such a thin fabric result from Evolon® high technology.
