IES 2000			Foam

		For detailed product specs see our NEW site at http://www.artusaindustries.us IES 2000 Foam. IES offers a wide variety of Foam products to meet the acoustical needs of virtually any space.  Our foam products include treatments for both walls and ceilings, absorptive and composite (absorber plus barrier), and can be combined to solve or correct any acoustical problems. Our products are manufactured to meet the specific requirements of your needs.  We can custom cut foam for size, thickness and acoustical properties desired. The standard foam configurations are in 2x2, 2X4panels or rolls usually 54" X 25 or 50 LF. You can find 3 foam product lines on this site Acousti-Composite, Acousti-Pad and The SONEX line

Foams and Composites

Acousti-Pad Foam
Acoust Pad acoustical foams are designed to provide maximum absorption of airborne sound with minimum thickness and weight. These foams are three to four times more absorbent than carpeting or standard ceiling tiles and come in standard sheet sizes. They also provide excellent performance and easy installation. These fine acoustical foams are available in a wide range of thicknesses and NRC ratings. We offer various utilitarian and decorative coatings including a perforated vynil.

Acousti-Composite ™ Foam
Acoust Composite™ acoustical foams combine dense limp, flexible, non lead loaded barriers with Acousti Pad to provide a total noise treatment solution. 

SONEX (sound absorbers and noise barriers)

Sonex™ Foam
Sonex™ acoustical foams let you create your own “quiet zone”. Sonex™ acoustical foam is a special sound-absorbing foam with a sculptured design that effectively traps sound. Sonex foams are over four times more absorbent than carpeting or standard ceiling tiles. Sonex™ acoustical foams are offered in two different materials and several different patterns to serve your sound-absorption needs. Sonex™ acoustical foams come in standard sheet sizes and can come with decorative coatings (hypalon or painted) to fit your application needs. All of the Sonex™ acoustical foam materials provide excellent performance and easy installation. The Sonex class 1 fire rated foams meet the most stringent public building codes nationally and locally. The same great acoustical performance is also offered in the traditional Sonex open celled polyurethane foam. Unique surface patterns of the acoustical foam deflect sound waves and convert the noise energy into quiet, kinetic energy. Sonex™ acoustical foams are available in a wide range of thicknesses, colors and patterns with sound absorption ratings ranging from NRC .75 – 1.10.
Choose SONEX for out of the box or IES installed application Sound Absorber and Noise Barrier foam. These are prepackaged component products. The SONEX line includes more than foam.

There are many types of common Polymer Foams: Polystyrene (used mainly as a technical filling, slicing, or packing foam Expanded grades are used in packaging and have a density ranging from 15 to 30 kg/m³.), Neoprene,The basic chemical composition of Neoprene synthetic rubber is polychloroprene.  Neoprene is available as a solid and as a liquid dispersion in "soft" and "hard" forms it is used for many things including machine glides / isolators and wet suit (it has replaced many hydro carbon rubbers). Polyethylene, Polyethylene is probably the polymer you see most in daily life. Polyethylene is the most popular plastic in the world. It is the polymer that makes our alum-a-frame liner, our rigid roll liner as well as  grocery bags, shampoo bottles, children's toys, and even bullet proof vests. For such a versatile material, it has a very simple structure, the simplest of all commercial polymers. Polyester-based Polyurethane, Polyether-based Polyurethane, and others.  Each is a synthetic plastic with two very desirable properties: easily malleable or shapeable , and capable of  “giving” and returning to its original shape. Most contemporary acoustical foams are Polyether and Polyester Polyurethane Foams,  Polyester Hydrophilic Foams (soft & water loving) or melamine.

HISTORY:  The First plastic was developed shortly after the American Civil War by John Hyatt and was named celluloid.  As an all-purpose plastic, celluloid found use in applications as far ranging as buttons, combs, and billiard balls.  It’s claimed that Hyatt played a large part in preserving the African elephant , since one of the major materials celluloid replaced was ivory.

More than fifty years passed before plastics grew to assume commercial importance.  In 1909, L.H. Backelund developed  Bakelite , which soon became widely used in insulation, phonograph records , and decorative applications.  Bakelite’s success turned plastics research from a laboratory curiosity into a major growth industry.  There were, it seems, big dollars to be made.

The birth of Polyester foam:  The plastics research, along with parallel breakthroughs in the development of a synthetic rubber, led almost by accident to the creation of commercially usable foams. The first was polyester-based polyurethane foam (now known as ester foam), developed in Germany during the late 40’s and early 50’s and because of its low tech production method is still marketed today. It  

is used principally because of its high tear resistance and tensile strength.

The birth of Polyurethane foam:  In the late 50’s, Polyether-based polyurethane foam (now know as polyurethane foam) cleared its last hurdle toward commercial production.  There had been problems with stabilizing the foam during the curing process ,   where the foam fixes.  But the refinement of a new silicon brought polyurethane foam into full-scale production. In effect, polyurethane

is spongier, more yielding, and stands up better to humidity than ester foam.

Polyurethane vs. Ester:  Polyurethane (Ether) foam shows advantages over the older, Ester foam:

1.      Greater stability in humid environments.  Dampness promotes ester foam disintegration.

2.      The different raw materials used to manufacture Polyurethane foam usually cost less than those used to manufacture Ester foam.

3.      Ester foam’s rough, scratchy surface is usually less desirable than the smoother, softly polyurethane surface.

4.      Although both materials are Open Cell, Ester foam cells are generally smaller in structure; therefore they have a tighter airflow.  In effect, polyurethane is spongier and more yielding than ester foam.

WHAT IS POLYURETHANE FOAM

Component chemicals.  Polyurethane form is a mixture of several chemicals:

POLYOL is an organic compound with a high molecular weight.  Polyol makes up the largest percentage of the foam formulation.

TDI, (toluene disocyanate) is an organic compound of lower molecular weight than polyol. TDI forms an exceptionally strong cross-link structure with the polyol, almost a super molecule.

Water reacts with the TDI to release carbon dioxide gas, which helps the mixture rise.

Freon II and Methylene Chloride these compounds boil to add additional gas to the mix.  Without the gas from these compounds, the foam would be very hard.

Amine-Type Catalyst helps to energize the water/TDI reaction.

Organo-Tin Catalyst helps to energize the polyol/TDI reaction.

These seven main ingredients make up the basic foam formulation.  The extra proportions depend upon just what type of foam is being produced.  Other chemicals can be added for special purposes: color, combustion modification, high resiliency, ect.

MELAMINE
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 bi-products associated with conventional polyurethane based acoustic foams.

Melamine foam is fibre and CFC free as well as having excellent fire resistant ratings. This foam can be used with excellent results in applications such as offices, halls, classrooms, nurseries, shooting ranges etc. The multi plane surface panels are usually produced in pairs, i.e. cut positive and negative.
