The professional insulation for noise absorption.
ArmaSound is a versatile acoustic absorber designed for use in a variety of different acoustic applications. A high performance sound absorber which also offers additional transmission loss performance and both vibration damping and isolation properties, ArmaSound is the result of 4 years of research. The acoustic properties of ArmaSound vary depending on formulation, density and thickness. The best results will be observed by selecting the most appropriate product grade for the type of noise in question. ArmaSound can also be engineered to meet specific requirements by optimising its absorption behaviour to match particular problem frequencies.
Sound Absorption
Open cell structure with complex pore geometry allows for effective absorption of air-borne sound across a broad frequency range
Unique combination of physical properties allows absorption to be maximised at key nuisance frequencies.
Sound Transmission Loss
Relatively high density and high flow resistance offers benifi cial sound tranmsission loss properties.
May be suitable for use as an alternative to complex "foam-barrier" multilayers.
Vibration Damping and Isolation
Visco-elastic properties help dampen or deaden resonance effects in metal panelwork (e.g. enclosures or ducting) which helps to reduce "re-raditaion" effects.
Reduces structure-borne noise transmission when used as isolation pads. |

High level of acoustical and thermal insulation. The foam has high working temperature. The low thermal conductivity and the high sound absorption
coefficient make the material specially suitable for the insulation of all types of hull and when lightweight is required. The final product is easy to cut in the right dimensions and can be easily fixed with glue or pins. The foam can be hydrophobic (H version) and covered with different foils aluminium, hydrophobic & oleophobic vlies, adhesive...). The grey colour variation has no effect on the product performances.

Divinycell F is the new low FST (fire, smoke and toxicity) core
material from DIAB that has been specifically developed for commercial
aircraft and public transportation. It more than exceeds the
USA and European regulatory requirements for aircraft interiors.
Also it meets the latest European fire standards for passenger
trains. Other key features include 200°C (392°F) processing
temperature, superior damage tolerance, exceptional fatigue life,
low water absorption and excellent heat ageing at 180°C (356° F).
Resistance to the majority of aircraft fluids is also excellent.

| The Divinycell range of polymer foam cores is the most comprehensive available. Each grade has been developed so that it meets a specific set of performance criteria. This allows designers, engineers and composite manufacturers to select the most appropriate material for their specific application. If you need a general purpose material then Divinycell H will probably meet your requirements. Need excellent FST (fire smoke and toxicity) properties then look no further than Divinycell F or P. Each grade is also available in a range of densities so that you can fine tune your selection. All grades are also available in a range of finishes to facilitate installation, enhance component quality and to meet process requirements. For series production, all Divinycell cores can be supplied in ready-made construction kits. |
