Automobile Damping and Silencing Sheet DC40-01A3 Purple

Short Description:

The automobile damping and silencing pad is an accessory used to reduce or eliminate the noise during brak-ing. It is an important component of the automobile brake pad. It is arranged on the steel back of the brake pad. When the brake pad is braking,it plays a certain damping effect on the vibration and noise caused by the brakepad pad pad. The brake system is mainly composed of brake lining (friction material), steel back (metal part) and damping and silencing pads.

Products Description

Automotive shock absorbing and sound deadening pad is an accessory used to reduce or eliminate noise when braking. It is an important part of automobile brake pads and is installed on the steel backing of the brake pads. When the brake pads brake, it plays a certain role in damping the vibration and noise generated by the brake pads. The brake system mainly consists of friction lining (friction material), steel backing (metal part) and vibration damping mat.

Silencing principle: Brake noise is generated by the friction vibration between the friction lining and the brake disc. The intensity of the sound wave changes once when it passes from the friction lining to the steel backing, and again when it passes from the steel backing to the damping pad. The phase impedance between the layers and the avoidance of resonance help to reduce noise.

Product Features

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 different customer requirements. It is a cost-effective alternative to imported materials with good vibration and noise damping effects.

The surface of the material has been treated with anti-scratch treatment, which has high strength and anti-scratch performance, and the surface color can be customized to red, blue, silver and other non-transferable colors according to customers' needs. According to customer demand, we can also produce cloth-coated panels without any texture.
