Noise Reduction Foam Tapes (NVH)
-- Steady & Reliable Manufacturer --
Detailed Product Description
Noise Reduction Foam Tapes, essential for NVH (Noise, Vibration, and Harshness) control, are viscoelastic materials designed to absorb and dampen structure-borne and air-borne energy. These tapes typically use medium- to high-density foam carriers (such as PU, high-density EPDM, or specialty closed-cell PE foam) with optimized cell structures to dissipate kinetic energy.
The mechanism of noise reduction is twofold: Absorption (converting sound energy into heat within the foam matrix, measured by the Noise Reduction Coefficient or NRC) and Dampening (dissipating vibrational energy when adhered to a panel, reducing rattle and resonant frequencies). These tapes feature a high-performance, vibration-absorbing acrylic or rubber-based adhesive to ensure intimate, permanent contact with the substrate, which is vital for the effective transfer and dissipation of vibrational energy across the bond line.
Performance is frequently tested under severe conditions, including extreme temperature cycles and continuous vibration (e.g., SAE standards for automotive applications), ensuring the tape maintains its viscoelastic properties and bond integrity throughout the product lifecycle.
Why Choose Us
Advantages and Core Features
- Efficient Vibration Damping: The high loss factor of the foam and viscoelastic adhesive effectively converts mechanical vibration energy into negligible heat, significantly reducing structure-borne noise and panel resonance (rattle).
- High Acoustic Absorption: Open-cell or specialized closed-cell structures are engineered to maximize sound wave capture and dissipation, resulting in a measurable reduction in air-borne noise (high NRC value).
- Consistent Compression Set Resistance: The foam maintains its thickness and resilience over long periods, ensuring continuous contact and isolation between components, which is critical for long-term anti-squeak performance in dynamic environments.
- Adaptable to Irregular Surfaces: The foam's conformability allows it to be installed easily on curved or uneven metal stampings and plastic moldings, ensuring 100% contact area for maximum dampening performance.
- Broad Operating Temperature Stability: Tapes are formulated to maintain their viscoelastic properties and adhesive performance across wide temperature extremes, ensuring continuous NVH control in engine compartments and outdoor machinery.
- Cost-Effective Mass Production: Supplied in continuous rolls or precision die-cut pieces optimized for high-volume, automated assembly processes common in large OEM operations.
Core Features
Application Areas
- Automotive Interior Panels: Placed between plastic panels, dashboards, and door cards to eliminate squeaks and rattles caused by vehicle movement.
- Appliance Motor Mounts: Isolating refrigerator compressors, washing machine motors, and HVAC fans to prevent the transmission of structure-borne vibration to the casing.
- Electronic Enclosures: Lining the inner surfaces of plastic or metal computer and server cases to dampen panel vibration and reduce fan noise.
- Office Equipment: Used in printers, copiers, and machinery to reduce the operational noise levels and improve the working environment.
- Window and Door Frames: Providing an acoustic seal to block air-borne sound transmission around the perimeter of building elements.

Frequently Asked Questions
Frequently Asked Questions (FAQs)
- Q: What is the primary difference between sound absorption and sound dampening?
- A: Sound absorption reduces airborne noise (e.g., room echo) and is measured by NRC. Sound dampening reduces structure-borne noise (e.g., panel rattle or motor vibration) and is measured by a loss factor, which indicates the material's ability to dissipate vibration energy.
- Q: How is the 'anti-squeak' function achieved in automotive applications?
- A: Squeaks and rattles are friction-induced noises. The foam tape is placed between the two moving surfaces (e.g., plastic and metal) to separate them, while the soft, non-abrasive foam material absorbs the micro-movement, eliminating the friction and subsequent noise.
- Q: Do these tapes require specific mounting conditions to work effectively?
- A: Yes, the tape must be applied firmly to the vibrating substrate to ensure the viscoelastic adhesive fully couples the foam to the surface. Poor adhesion will negate the damping effect, as energy transfer will be inefficient.
- Q: Can a foam tape provide both sealing and NVH control?
- A: Yes, provided the foam is closed-cell. The dense structure can block air/water (sealing) while the foam's elasticity can simultaneously absorb mechanical vibration (NVH), offering a dual-function solution for enclosures.
