Automobile Damping and Silencing Sheet DC40-02A6

Short Description:

Automotive damping and soundproofing pads are specialized accessories designed to minimize or eliminate noise during braking operations. As an integral component of automotive brake pads, these pads are strategically positioned on the steel backing of the brake assembly. When the brake system engages, these pads effectively dampen vibrations and suppress noise generated by the brake pads, ensuring a quieter and smoother driving experience. The brake system typically comprises three main elements: the brake lining (friction material), the steel backing (metal component), and the damping/soundproofing pads.

Products Description

Automotive shock absorbing and sound deadening pad is an accessory used to reduce or eliminate noise during the braking process of an automobile. It is a key component of automobile brake pads and is fixed on the steel backing of the brake pads. It acts as a cushion for the vibration and noise generated by the brake pads when the brake pads are braking. The automobile brake system is mainly composed of friction linings (friction materials), steel backing (metal parts) and vibration and noise damping pads.

Noise reduction mechanism: The noise generated during braking originates from the friction vibration between the friction lining and the brake disc. The sound waves undergo an intensity change when they travel from the friction lining to the steel backing, and another intensity change when they travel from the steel backing to the damping pad. The difference in phase impedance between the layers and the avoidance of resonance can effectively reduce noise.

Products Feature

The thickness of the metal substrate ranges from 0.2mm - 0.8mm with a maximum width of 1000mm and the thickness of the rubber coating ranges from 0.02mm - 0.12mm. Single and double sided NBR rubber coated metal materials are available to meet the diverse needs of different customers. It has excellent vibration and noise damping properties and is a cost-effective alternative to imported materials.

The surface of the material has been treated with anti-scratch treatment for excellent scratch resistance, and the surface color can be customized according to customers' requirements in red, blue, silver and other opaque colors. According to customer requirements, we can also produce cloth-coated sheets without any texture.
