How Recycled Melamine Foam Revolutionizes Soundproofing in Construction and Automotive Industries
Noise pollution is a rising concern in both buildings and vehicles. Traditional materials like fiberglass or vinyl may block some sound, but they often fall short when balancing performance, safety, and sustainability. Enter SINOYQX’s Recycled Melamine Foam—a high-density soundproofing solution (35–120 kg/m³) designed to block noise transmission while meeting modern environmental and safety standards.

🔇 What Makes Recycled Melamine Foam an Effective Soundproofing Material?
Unlike open-cell acoustic foam used for sound absorption, SINOYQX’s recycled melamine foam is formulated for noise insulation—it prevents sound from traveling between spaces or compartments.
Key soundproofing advantages include:
High sound transmission loss (STL)
Good compression strength and vibration damping
Flame retardant (B1-rated), non-fibrous, and low VOC
Wide operating temperature: from -180°C to +240°C
Environmentally sustainable: made from reclaimed melamine foam scrap
Thanks to its closed/semi-closed structure and increased bulk density, this recycled material performs exceptionally well in multi-layer barrier systems and enclosures.

🏢 Building Applications: Effective Sound Blocking for Walls & Equipment
1. Commercial Building Partition Walls
SINOYQX recycled melamine foam panels (50 mm thick, 80 kg/m³) were installed between drywall systems to increase STC (Sound Transmission Class) ratings. Result: over 20 dB reduction in noise leakage from adjacent conference rooms and lobbies.
2. Mechanical Room Enclosures
In HVAC rooms and generator spaces, the foam was used as a sound barrier liner within metal cabinets. Its dense, thermally stable structure helped isolate machine noise and reduce resonance, without adding significant weight.
3. Prefabricated Modular Units
Recycled melamine foam was laminated with aluminum foil and used in prefabricated wall panels of mobile medical units. It replaced heavier MLVs while providing both thermal insulation and structure-borne soundproofing.

🚆 Transportation Applications: Blocking Noise in Rail and Commercial Vehicles
1. Train Car Wall Cavities
To improve passenger comfort, high-density recycled melamine foam was placed behind internal paneling. It blocked track and engine noise, enhanced flame safety (meeting B1 standards), and reduced overall system weight versus traditional rubber sheets.
2. Truck Cab Insulation
Truck OEMs integrated compressed recycled melamine foam (≥100 kg/m³) in floor and engine bay partitions to isolate drivetrain noise. Unlike fiberglass, it is non-toxic, easy to cut, and maintains structure under long-term vibration.

🔍 Material Comparison for Soundproofing
Material Sound Blocking (STL) Fire Rating Density Range (kg/m³) Recyclable Notes
Recycled Melamine Foam High (when layered) B1 / V-0 35–120 ✅ Yes Light, clean, flame retardant
Mineral Wool / Rockwool Medium A1 40–120 ♻️ Limited Irritating fibers, heavy
