YDNFoam™ Melamine Foam – Premium Noise Reduction for Electric Shavers
In the premium electric shaver market, quiet performance has become a core buying factor. Today’s consumers expect powerful shaving with minimal high-pitch noise, especially in early morning or office use.
YDNFoam™ ultra-light melamine foam offers a proven way to deliver a quieter, more comfortable shaving experience, helping brands compete at the highest level.

The Noise Problem in Electric Shavers
Even top-tier global brands like Philips, Braun, and Panasonic face high-frequency noise challenges in the 1–10 kHz range — the most sensitive range to the human ear.
Main causes include:
Motor electromagnetic noise (especially from brushed motors)
Blade head collision and friction
Housing resonance and vibration
PWM switching noise from electronics
Traditional solutions like motor swaps can help, but they often fail to address high-frequency noise effectively.

Why YDNFoam™ Melamine Foam is Different
YDNFoam™ is a microcellular, ultra-light acoustic foam designed to target high-frequency noise in compact devices such as electric shavers.
Core Benefits:
Targeted absorption – 1–10 kHz frequency range
Lightweight – 4–6 kg/m³ density
Slim – 2–5 mm thickness for tight spaces
Compliant – Low VOC, odor-free, UL 94 V-0, REACH, RoHS
Durable – Antimicrobial, mold-resistant, heat- and moisture-resistant

Strategic Application Points
Motor Housing Liner – reduces electromagnetic noise at the source
Blade Head Cover Ring – cushions and quiets blade movement
Circuit Module Patch – suppresses PWM switching tones

Proven Performance
When paired with a brushless motor, YDNFoam™ integration delivers ≥10 dB total noise reduction, transforming sound from a sharp buzz into a soft, premium tone.
Breakdown:
Brushless motor: –5 to –7 dB
YDNFoam™ acoustic liner: –3 to –5 dB
Combined: ≥10 dB

Why YDNFoam™ Beats Generic Foam
Unlike PU or PE foams, YDNFoam™ maintains acoustic efficiency in thin profiles, resists heat and humidity, and passes global safety and environmental standards — without off-gassing odors.

Easy to Integrate
Custom die-cut or laser-cut shapes
Self-adhesive for fast placement
Thermoformed parts for complex curves
Can be pre-installed at component supplier level to save assembly time

The Competitive Advantage
Using YDNFoam™ melamine foam for electric shaver noise reduction allows brands to:
Outperform competitors in quiet technology
Differentiate mid-tier products with a premium sound signature
Increase perceived product value by up to 15%
