Lightweight Vibration-Damping Plate

APPLICATION SCENARIOS

1. Inner layer of car doors, providing vibration damping while reducing the overall vehicle weight  

2. Roof and pillar areas, suppressing resonance and improving riding quietness  

3. Tailgates and trunk lids, reducing vibration to prevent abnormal noise  

4. Battery compartment covers of electric vehicles, providing lightweight sound insulation protection

Product Description

This series of automotive vibration damping sheets (also known as damping pads or shock absorbing plates) are made of butyl rubber and aluminum foil composite material, with a composite loss factor of ≥0.2 and a density of ≤1.0g/cm³, combining lightweight properties with good vibration absorption and noise reduction performance. The product is widely applicable to vibration-prone parts such as car doors, chassis, and trunks, effectively suppressing sheet metal vibration. It has advantages including anti-aging, moisture resistance, and being not easy to fall off. With simple construction, it adapts to various vehicle structures, helping to comprehensively improve the vehicle's NVH performance and driving/riding comfort.

PRODUCT FUNCTION

Dual-effect design for vibration absorption and noise reduction: Utilizes the butyl rubber structure to absorb and attenuate vibration energy, reducing resonance noise;  

Lightweight damping solution: Low-density design (≤1.0g/cm³) reduces overall vehicle load, suitable for weight-sensitive new energy vehicles or sports cars;  

Durable and stable: Anti-aging, moisture-proof, with no edge warping or hardening after construction, applicable to long-term use scenarios;  

Convenient construction experience: Equipped with release paper backed adhesive design, directly adheres to metal sheet metal, supporting free cutting and fitting on complex curved surfaces.

PERFORMANCE INDEX

Composite loss factor: ≥0.2 (with basic to moderate vibration absorption capability)  

Density: ≤1.0 g/cm³ (lightweight design, reducing overall vehicle load)  

Applicable temperature range: -40℃ ~ 80℃  

Recommended construction temperature: 10℃ ~ 40℃  

Adhesion performance: Adapts to vehicle body curved surfaces, adhering tightly without hollowing  

Structural composition: Butyl rubber damping layer + aluminum foil reflective layer + pressure-sensitive adhesive backing + release paper  

Environmental compliance: Can provide certified versions compliant with environmental standards such as RoHS and REACH

APPLICATION AREA

This product is suitable for sheet metal vibration suppression and interior noise control of various automotive structural components. Typical applications include:  

Inside door panels: Reduce door panel resonance and external noise penetration;  

Trunk area: Suppress rear structural resonance and reduce low-frequency echo;  

Chassis and floor: Absorb vibrations from the bottom during driving, improving driving quietness;  

Wheel arches or engine compartment partitions: Used in conjunction with sound insulation cotton to block wind noise and mechanical noise;  

Lightweight noise reduction parts of new energy vehicles: Meet special application scenarios sensitive to weight but requiring noise reduction.
