Polyurethane foam (PU foam)
Fibers & Foams offers a wide selection of polyurethane foam (PU foam), specifically known as polyether foam. These foams are offered under the name EASYfoam. You have the choice of various finishes, dimensions, and thicknesses. EASYfoam is easy to order online and is delivered directly from stock.
Wat is polyurethane foam?
Polyurethane foam, often abbreviated as PU foam, is a commonly used material produced by the reaction of polyol and diisocyanate. This results in a versatile foam with different properties depending on the raw materials and production methods used. Polyurethane foam is known for its lightness, flexibility, and insulating properties. It is used in a wide range of applications including insulation, furniture, mattresses, packaging, and sound insulation. In the context of sound insulation, polyurethane foam can be used as acoustic foam to absorb sound and improve the acoustics of a room.
Applying polyurethane foam.
Acoustic foam, also known as sound foam or sound insulation foam, has an open cell structure that absorbs and dampens sound. Online, you can also find PU acoustic panels with a closed cell structure, but these do not offer sound insulation properties.
This foam is used in various ways. Firstly, it is used as sound insulation foam for hollow spaces, such as cavity walls (not suitable for damp spaces or exterior walls), and for the construction of sandwich panels where the sound foam is enclosed between two plywood or MDF sheets.
Secondly, it is used as acoustic foam to prevent reverberation and resonance chamber formation, for example in enclosures around noisy equipment such as pumps or ventilation ducts, and in engine compartments.
Thirdly, it can be used to improve the acoustics of a space, especially in sound studios, hence the nickname "studio foams". It can also be applied in server rooms by installing it on the walls to create a quieter environment.
Properties of polyurethane foam
The PU foam we offer is known for its excellent acoustic quality due to its high specific weight. It is delivered in the form of acoustic panels and has a lifespan of approximately 5 to 10 years, depending on the application. Examples include use under a bonnet or in areas with a lot of sunlight, where it can age faster than in a server room.
Furthermore, we offer acoustic foam with special top layers that are resistant to oil and water splashes. An example of this is EASYfoam PU, with a top layer that is suitable for oil and moisture splashes.
Our polyurethane-based acoustic foam is flame retardant according to FMVSS 302 and UL-94 Class HF1. This makes it suitable for applications where high demands are placed on fire safety. In contrast to polyether foams, which are not recommended for use in public spaces due to these strict fire safety requirements.
Different finishes and variations.
EASYfoam panels are available in different variants. All variants are available in different thicknesses because the thickness of the sound-insulating foam is an important factor for the acoustic quality. In general, the rule is: the thicker, the better the sound is absorbed. Detailed information about the absorbing properties of each variant can be found on the product page.
In addition, we offer acoustic foam in various structures, such as dimple, pyramid, or flat foams (TC2). Some variants come with a top layer that provides extra protection against oil or water splashes, such as EASYfoam PU or AC2. These variants are suitable for use in machine rooms or enclosures of water pumps.
All variants are equipped with a self-adhesive backing for easy installation. Of course, we are always ready to help you choose the right variant for your specific needs!
