Acoustical Polyester Urethane Foam sound absorbing Products

Polyurethane Foam

Polyester Urethane Foam sound absorbing product, is a 2 lb. per cu. ft. (32 kg/m3) density polyester urethane foam developed to absorb maximum acoustical energy, using minimum weight and thickness. Sound ¡s absorbed over a broad frequency spectrum with peak efficiencies above the 500 Hz frequency level. Polyester Urethane Foam is charcoal grey in color with a consistent small open-cell structure to provide maximum sound absorption. The material is very clean to handle and is non-toxic and non-irritating. Because of high tear and shear strength properties, it can be supported with a minimum of mechanical fasteners. It can be attached by adhesive to most types of hard reflective surfaces and also furnished die-cut to any irregular shape, and can be easily cut with a utility knife or scissors. Standard thicknesses are 1/4” through 2” (6 mm through 51 mm).

Polyester Urethane Foam is available with special facings for protection against oils, dirts, and moisture, and is also available with pressure-sensitive adhesive backing for ease of installation where the material is to be applied by bonding.


Polyester Urethane Foam is an absorbing used to reduce the energy of reflective and/or reverberate sound waves in the middle and high frequency ranges. When used as a decouple of two masses, such as for wrapping duct work or pipelines prior to the use of secondary barrier materials such as mass-loaded vinyl products, it increases the Sound Transmission Class (STC) of the system. It may be used in baffle form above open-top enclosures where it is necessary to reduce reverberate sound levels created by reflection from hard surfaces.

Product Specifications

Acoustical absorption material shall be polyester-type, urethane foam having an NRC Rating of 0.35 for 1/4” (6 mm) thickness, 0.54 for 1/2” (1 3 mm), 0.75 for 1 “(25 mm), or 0.90 for 2” (51 mm) thickness.

Acoustical absorption material shall have a life service expectancy of ten years under normal applications, and shall be rated #94 HF-i in accordance with UL #94 Flame Retardancy Tests.

When used in environments where the open cells of the foam can be filled or contaminated with oil, oil mists, dirt, dusts, and water, the exposed surface shall be faced with a thin film of either Urethane, Ted lar, or Mylar to protect against this contamination.

Material shall have a density of 2 lbs./cu. ft. (32 kg/m3) and shall be manufactured by Polyester Urethane, Inc.

The optional film facing provides protection in applications involving dust, oil mist, and moisture without detracting from the acoustical properties of the foam.
