Vibration Damping Plate

APPLICATION SCENARIOS

1. Inside of car doors, reducing sheet metal vibration and wind noise  

2. Under the hood, reducing engine noise transmission into the cockpit  

3. Chassis and wheel arch areas, reducing road noise and stone impact noise  

4. Trunk and tailgate areas, improving overall vehicle sound insulation comfort

Product Description

This series of automotive vibration-damping plates (also known as damping sheets or shock-absorbing plates) adopt a composite structure of butyl rubber and aluminum foil, featuring excellent damping and shock-absorbing performance. By directly attaching to the surface of thin metal plates such as car doors, chassis, and trunks, they effectively reduce resonance and the transmission of noise sources, improving the overall IVH performance of the vehicle. The product has good flexibility and anti-aging ability, with convenient construction that requires no professional tools. It can be cut and pasted as needed, adapting to various vehicle structures.

PRODUCT FUNCTION

High damping and vibration absorption: The butyl damping layer absorbs and dissipates vibration energy, inhibiting sheet metal resonance;  

Significant noise reduction effect: When used with sound insulation materials, it comprehensively reduces road noise, wind noise, engine noise, etc.;  

Highly conformable design: Adaptable to complex sheet metal curved structures, with no edge warping or hollowing after pasting;  

Anti-aging, moisture-proof and anti-shedding: No hardening or oil seepage during long-term use, maintaining stable performance;  

Tool-free construction: Equipped with release paper backed adhesive design, ready to use after peeling and pasting, facilitating personalized cutting and installation.

PERFORMANCE INDEX

Composite loss factor: ≥0.15 (indicating excellent damping performance)  

Applicable temperature range: -40℃ ~ 80℃  

Optimal construction temperature: 10℃ ~ 40℃  

Structural composition: Butyl rubber base material + aluminum foil surface layer  

Adhesion performance: Can achieve tight bonding without bubbles or gaps on clean sheet metal surfaces  

Environmental requirements: Non-toxic and odorless material, compliant with automotive interior environmental requirement standards (REACH / RoHS versions customizable)

APPLICATION AREA

Widely used in noise reduction and vibration resistance systems of various vehicle types including but not limited to passenger cars, commercial vehicles, and new energy vehicles:  

Inner door panels — Reduce door panel vibration and external noise penetration;  

Underbody and floor panels — Isolate road noise and low-frequency vibration;  

Trunk and wheel arches — Block rear resonance noise and gravel impact noise;  

Engine compartment shields — Suppress structural vibration and heat-induced resonance;  

Roof and firewall areas — Enhance overall vehicle quiet comfort and driving quality.
