Damping Gasket with Thermal and Sound Insulation Performance

Damping sheet, also known as mastic or damping block, is a kind of viscoelastic material attached to the inner surface of the vehicle body, which is close to the steel plate wall of the vehicle body. It is mainly used to reduce noise and vibration, that is to say, damping effect. All cars are equipped with damping plates, such as Benz, BMW and other brands. In addition, other machines that need shock absorption and noise reduction, such as aerospace vehicles and airplanes, also use damping plates. Butyl rubber composes metal aluminum foil to form vehicle damping rubber material, which belongs to the category of damping and shock absorption. The high damping property of butyl rubber makes it a damping layer to reduce vibration waves. Generally, the sheet metal material of vehicles is thin, and it is easy to generate vibration during driving, high-speed driving and bumping. After the damping and filtering of the damping rubber, the waveform changes and weakens, achieving the purpose of reducing noise. It is a widely used Efficient automobile sound insulation material.
