Kinetics Composite Acoustical Materials are a group of limp, flexible, noise barrier materials laminated to Kinetics urethane absorption foam.
All products are available with or without pressuresensitive adhesive on the foam surface.
The composites are designed for attachment to surfaces of rigid enclosures to provide a Sound Transmission Class (STC) value which exceeds the performance of materials of the same mass if bonded directly to a surface.
Model KC-5-50 consists of 0.5 lbs./sq.ft. (2.5 kg/m2) loaded vinyl barrier bonded to 1/2" (13 mm) thick urethane absorption foam. Model KC-10-100 consists of 1.0 lbs./sq.ft. (4.9 kg/m2) bonded vinyl barrier bonded to 1" (25 mm) thick urethane absorption foam. Model KC-5-50/100 consists of 0.5 lbs./ sq.ft. (2.5 kg/m2) loaded vinyl barrier bonded to 1/2" (13 mm) thick urethane absorption foam on one side and to 1" (25 mm) thick urethane absorption foam on the other side.
Under normal circumstances, the foam surface on the single composite and the 1/2" (13 mm) foam surface on the double composite are attached to the enclosure.
Model KC Composites are easily cut with a utility knife, scissors, or die-cut into custom configurations.
Model KC Composite Materials are recommended for direct attachment to noisy equipment casings. When applied to a radiating surface, the absorption foam is placed toward the surface to "decouple" the limp mass thus providing an increase in Sound Transmission Class (STC).
Kinetics Composites can be suspended in limited lengths as a barrier around noisy equipment with the absorption surface facing the noise source.
Typical applications include:
- Exterior wrapping of gear boxes
- Pipeline jackets
- Sheet metal guards, ducts, and enclosures
- Pile driver enclosures
- In-plant processing equipment
- Curtain or barrier systems
- Pressure-sensitive adhesive backing on the foam side. Add "A" to the product name.
- Urethane facing on the foam side. Add "U" to the product name.
- Tedlar facing on the foam side. Add "T" to the product name.
- Mylar facing on the foam side. Add "M" to the product name.
- Because there are (2) foam surfaces on KC-5-50/100, please specify which surface the optional feature is to be applied on.
