Damping

DBL Damping Sheets (DBL) is a self-adhesive, lightweight damping pad material used for controlling noise and vibration in truck, bus and industrial machine sheet metal applications. The pad material is odorless, wear resistant, waterproof and provides damping performance equal to that of conventional materials twice its weight.

Noiseless Rigid Urethane Flooring (NRUF) is laminated Urethane Board designed to reduce vibrations and noise transmission in flooring constructions. It consists of two sheets of Urethane Boards bonded together by a thin viscoelastic damping layer.

dBdamp MP damping foils and sheets use the constrained layer principle to reduce resonant structural vibrations in the supporting panels.

Replacing normal plywood with Noiseless Wood improves the transmission loss in two critical regions. First: at the resonance frequencies of the structure the peak vibration levels are reduced about 10 fold. Second: at mid to high frequencies there is a phenomenon referred to as the coincidence frequency. This is the sound that has the same wavelength in air, as does the bending wave in the panel at the same frequency.

Noiseless Metal (NM) is laminated metal designed to reduce vibrations and noise transmission in metal constructions. It consists of two sheets of metal bonded together by a thin viscoelastic damping layer. NM can be made using any commercial quality steel or aluminum.

VEVO is a flexible viscoelastic damping material available in sheets and custom die-cut parts. It is designed to attenuate structural vibration energy over a temperature range of 12°C (10°F) to 77°C (170°F) offering maximum damping between 10°C (50°F) and 37°C (100°F). In addition to its outstanding damping characteristics, VEVO is highly resistant to most common chemicals (water, petroleum, mild acids and bases) as well as the environment (UV and ozone), while exhibiting excellent flame resistance and low smoke generation under fire conditions. VEVO is supplied with an integral, pressure-sensitive adhesive system, which requires only the removal of the paper release liner and application of pressure to assure an intimate and permanent contact with the substrate. This “peel and stick” adhesive system allows maximum performance and is especially suited to assembly line applications.
