High-Density Vibration Plate

APPLICATION SCENARIOS

1. Laid on underbody floor, enhancing low-frequency sound insulation effect  

2. Trunk bottom, blocking tire noise and resonance  

3. Engine hood and firewall area, improving engine noise isolation capability  

4. Inner layer of door and side panel sheet metal, reducing resonance and improving overall vehicle quietness level

Product Description

This series of automotive vibration damping sheets (also known as damping pads or shock absorbing plates) are made of a composite structure of butyl rubber and aluminum foil, with a composite loss factor of ≥0.25 and a density of ≥2.3g/cm³. Specifically designed to suppress vibration and noise transmission in sheet metal structures, they are widely used in vibration-prone parts such as car doors, floors, fenders, and trunks. The product features good conformability, moisture resistance, and anti-aging ability, with easy pasting and support for free cutting and curved surface installation. By optimizing the vehicle's overall NVH performance, it enhances the vehicle's quietness and driving/riding experience.

PRODUCT FUNCTION

High damping and vibration absorption performance: The butyl rubber layer effectively absorbs and disperses sheet metal vibration energy, especially suitable for areas with strong vibration (such as fenders, chassis);  

Multi-level noise reduction synergy: When used in combination with sound insulation cotton, it can significantly reduce multi-source noise such as engine noise, road noise, and wind noise;  

Long-lasting adherence and anti-aging: Non-hardening and non-shedding during long-term use, with excellent moisture and heat resistance;  

Flexible and convenient construction: Featuring a self-adhesive backing design, it can be directly pasted on clean metal surfaces, supporting free cutting and adapting to different vehicle structures.

PERFORMANCE INDEX

Composite loss factor: ≥0.25 (high damping performance)  

Material density: ≥2.3 g/cm³ (high compactness and excellent vibration absorption capability)  

Operating temperature range: -40℃ ~ 80℃  

Recommended construction temperature: 10℃ ~ 40℃  

Structural composition: Butyl rubber + aluminum foil + pressure-sensitive adhesive + release paper  

Long-term use stability: Anti-aging, moisture-proof, anti-hardening, non-oil-seepage, and no bulging after pasting  

Environmental compliance: Customizable versions compliant with environmental regulations such as RoHS, REACH, PAHs, TSCA, etc.

APPLICATION AREA

Suitable for sheet metal vibration damping and noise reduction systems of various vehicle models. Typical application scenarios include:  

Inside of car doors/trunk lids: Reducing body resonance and door panel reverberation;  

Floor and fender areas: Absorbing road noise and low-frequency vibration during high-speed driving;  

Wheel hubs/rear wheel arch positions: Blocking tire stone-splash noise and vibration transmission;  

Engine compartments and front wall structures: Reducing the transmission of engine vibration into the vehicle interior;  

Chassis and enclosed side wall structures: Enhancing overall vehicle quiet performance and structural stability.
