Melamine Foam (Basotect Foam): The Ideal Acoustic and Safety Material for Public Buildings

Dear procurement professionals in public buildings, stadiums, noise barriers, and commercial complexes:

Melamine foam is a high-performance, eco-friendly material that integrates superior sound absorption, permanent fire resistance, lightweight structure, and thermal insulation. It perfectly meets the stringent requirements of modern public buildings in terms of acoustics, fire safety, environmental protection, and structural efficiency.

It is an advanced alternative to traditional materials such as rock wool, glass wool, and polyurethane foam.

1. Core Performance Advantages (Key Procurement Considerations)

1.1 Full-Frequency Sound Absorption for Superior Acoustic Performance

• Three-dimensional open-cell structure (≥99% porosity) allows sound waves to penetrate deeply and convert into heat energy, eliminating secondary reflections.

• Outstanding sound absorption performance:

  • NRC (Noise Reduction Coefficient): 0.85–0.95

  • 50mm thickness: NRC up to 0.9

  • 80mm thickness: NRC up to 0.95

  • Mid-high frequency (200Hz–20kHz): ≥0.9

  • Low frequency (50Hz): absorption rate over 95%

Application Value:

• Stadiums: Reduce reverberation and improve speech clarity

• Shopping malls: Minimize crowd noise and enhance comfort

• Noise barriers: Reduce traffic noise by 20–35 dB

---

1.2 Inherent and Permanent Fire Resistance for Maximum Safety

• No flame retardants required; naturally meets:

  • GB8624 Class B1

  • UL94 V-0

  • EN45545 HL3

  • Oxygen Index ≥33%

• No dripping, low smoke, non-toxic combustion

• Forms a dense carbon layer that effectively blocks flame spread

Ideal for high-occupancy public spaces with strict fire regulations

---

1.3 Ultra-Lightweight to Reduce Structural Load and Installation Costs

• Density: only 6–12 kg/m³
  (Compared to rock wool: 30–100 kg/m³)

• Minimal load impact on roofs and walls

• Easier transportation and installation

Cost Benefit:
Reduces overall construction costs by 15–20%

---

1.4 Eco-Friendly and Clean for Green Building Standards

• Zero formaldehyde emission, no detectable TVOC

• Certified by RoHS, REACH, and French VOC A+

• No fiber shedding or dust—safe for enclosed and high-traffic environments

• Moisture-resistant and anti-aging

Service life ≥ 20 years without performance degradation

---

1.5 High Thermal Insulation for Energy Efficiency

• Thermal conductivity: 0.030–0.035 W/(m·K)

• Superior to traditional insulation materials

• Can be laminated with aluminum foil

Achieves integrated sound absorption + insulation + fire protection

---
