In developed countries, such as Europe and the United States, automotive dampers are made of macromolecule resin materials and rubber materials, which do not volatilize toxic and harmful gases. The green environmental protection damping patch is a kind of thin sheet patch made of damping material. It is used on the sheet metal of vehicles. Butyl rubber composite metal aluminium foil is used to compose the automotive shock absorber material. It belongs to the category of this kind of damping and shock absorber. Butyl rubber has high damping, which makes it a damping layer for reducing vibration wave. Generally, the sheet metal material of vehicles is thinner, driving at high speed and upside down. It is very easy to produce vibration when bumping. After the shock absorber is filtered, the waveform changes and weakens, which achieves the purpose of reducing noise. It is a widely used and efficient sound insulation material for automobiles.
