The Halogen-Free Flame-Retardant Vibration Damper is a high-performance engineered solution designed to eliminate structural resonance and suppress noise in demanding environments. By utilizing an advanced composite of butyl rubber and aluminum foil, this damping system effectively converts mechanical vibration into heat energy, significantly enhancing NVH (Noise, Vibration, and Harshness) performance for automotive, industrial, and electronic applications.
Engineered for maximum safety and environmental compliance, our dampers are formulated with eco-friendly halogen-free polymers, ensuring zero toxic gas emissions during high-temperature exposure. Meeting stringent global standards such as UL94 V0 and EN45455 R2, this product provides a critical layer of fire protection for battery compartments, power distribution modules, and precision machinery, balancing lightweight design with rugged durability.

Halogen-free materials do not contain bromine or chlorine. In the event of a fire, they do not release corrosive or toxic gases, significantly improving safety for passengers and operators and meeting strict environmental regulations.
The loss factor measures the material's ability to dissipate mechanical energy as heat. A value of ≥0.2 indicates high viscoelasticity, which effectively stops sheet metal from ringing and reduces structural resonance.
Yes, they are specifically designed for EVs. They provide essential sound insulation around battery compartments and power distribution modules while meeting the highest flame retardancy standards (UL94 V0).
Our dampers are stable across a wide operating temperature range from -40℃ up to +80℃, ensuring they remain flexible and adhesive in both extreme cold and high-heat industrial environments.
Yes, the composite structure includes an aluminum foil layer which not only adds structural integrity but also assists in heat dissipation and provides a moisture-proof barrier.
Absolutely. We offer comprehensive customization services to tailor the density, thickness, and dimensions of the damping sheets to meet the specific structural requirements of your equipment.
