The detached sound insulation cotton under the Civic chassis can be replaced with a new one or simply glued back using adhesive or silicone sealant. Below is relevant information about chassis sound insulation cotton: 1. Function: Installing sound insulation cotton under the car chassis provides comprehensive benefits including high adhesion, high wear resistance, impact resistance, rust prevention, corrosion resistance, and noise reduction. 2. Noise sources: The primary purpose of chassis sound insulation is to reduce road noise generated by friction between the tires and the ground, significantly enhancing driving safety for the owner. Applying vibration-damping strips and sound insulation cotton to the chassis effectively absorbs any vibrations and blocks heat transfer.
