Resonance vibration of metal panels is a common source of noise and annoyance in cab panels, housings and enclosures, sinks, rail cars and many other products. Antivibe® vibration damping materials can efficiently and economically reduce resonance vibration. This results in reduced noise and improved sound; reduced vibration transfer to adjoining structures; increased working life of the metal and other substrates by delaying the onset of fatigue due to resonance vibration; and the ability to use thinner metal without the need for ribs, shaping or other complications.
Antivibe® DL is a water-based, sprayable free layer vibration damping compound which has an extremely high loss factor and offers a low cost method for applying damping. Antivibe® DS is offered in sheet form, with or without adhesive backings. The free layer version is made from a specially designed polymeric multi-component formulation and is available with or without a pressure sensitive adhesive which has been developed to enhance the loss factor. Antivibe® DS also has a constrained layer version. Here, a metallic constraining layer such as aluminum foil is fabricated with the viscoelastic layer to provide enhanced vibration damping performance. Antivibe® vibration dampers can be custom engineered to provide peak vibration damping at various temperatures. When choosing a vibration damper, some properties which should be taken into consideration are: operating temperature and frequency range of interest, loss factor requirements, thickness, resistance to heat and chemicals, flammability, moldability and cost.
