Pressure sensitive viscoelastic polymer on dead soft aluminum foil or stainless steel. Use for sound or vibration damping on aircraft, conveyors, and mechanical devices. 3M viscoelastic damping polymer 112 series is a family of acrylic polymer based materials that are useful in many engineered designs. They have proven to reduce vibration and shock problems in electronics, appliances, automobiles and aircraft. These versatile materials can be adapted to a wide variety of applications including constrained layer dampers, multi-layer laminates using metal or polymeric films, free layer dampers, suspension dampers, shock and vibration isolators, panel, pipe and wing dampers and more.
