Description:
Kinetics Acoustical Foam, Model KUA 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 is absorbed over a broad frequency spectrum with peak efficiencies above the 500 Hz frequency level.
Model KUA 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.
Model KUA Acoustical Foam can be attached by adhesive to most types of hard reflective surfaces. It can be 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).
Kinetics Model KUA Acoustical 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.
Application:
Model KUA Acoustical Foam is an absorber used to reduce the energy of reflective and/or reverberant sound waves in the middle and high frequency ranges.
When used as a decoupler of two masses, such as for wrapping ductwork 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.
Model KUA Acoustical Foam may be used in baffle form above open-top enclosures where it is necessary to reduce reverberant sound levels created by reflection from hard surfaces.
The optional film facing provides protection in applications involving dust, oil mist, and moisture without detracting from the acoustical properties of the foam.
Thicknesses of up to 6" (152 mm) can be furnished on special order where low-frequency sound absorption is required.
