Melamine Foam For Thermal and Acoustical Insualtion

Posted by Second Skin on

Melamine Foam Insulation for Thermal Management and Noise Reduction

Melamine foam is an effective absorber suitable for applications involving noise control and thermal management. Second Skin Audio provides a range of melamine foam insulation for a variety of industries, mainly car audio, construction, rail transportation, heavy truck, aerospace, medical, and marine manufacturing. The foam is widely used because it is a versatile, flame resistant material that is lightweight, semi-rigid yet flexible, and easy to customize.

All grades of melamine foam are utilized for thermal and acoustical insulation applications. While standard melamine insulation can absorb water, all of Second Skin’s melamine products are hydrophobic (resistant to moisture and shed water).

Sound Reducing Insulation

The open cells in melamine foam make it an excellent noise reducing insulation because sound waves can travel deeply into the foam. Once there, the sound waves are converted to low-grade heat in the open cell structure of the foam, stopping noise from reflecting, causing echoes and increasing noise levels. Our foam is a popular sound reducing material for manufacturers as it absorbs mid to high range frequencies while meeting aircraft (FAA, BSS, etc), HVAC, and transportation vehicle’s flame, smoke, and toxicity standards.

Thermal Insulation

Melamine foam prevents the convection and heat transfer of air, making it an excellent insulator. The foam has a thermal conductivity of 0.25 BTU-in/ft²-hr-°F at 68°F and is often used for heating, ventilation, and air condition duct lining. Due to the rigid cell structure of the foam, it does not settle or fall apart over time, unlike fiberglass, and remains an effective insulator for years.

Extremely lightweight, the foam provides exceptional resistance to heat, low-flame, and smoke without adding excessive weight during application. Our foam meets all aircraft (FAA, BSS, etc.), HVAC and transportation (rail) flame, smoke, and toxicity standards. The foam is also available with a 1,000 degree thermal film facing (Mega Block) and pressure-sensitive adhesive backings.

Flame Resistant Materials for Safety

One of the key properties that sets melamine foam apart from other insulators is its flame resistance. Our foam can withstand temperatures between -300°F to 356°F and has an intermittent temperature range of up to +400°F. The fire-resistant characteristics are a result of the high nitrogen content in the melamine resin used to manufacture the foam. The resin creates an extremely flame-resistant insulation without the need of additional fire-retardant chemicals. Melamine foam does not drip or melt in the presence of open flame and exudes little smoke. Once the ignition and fuel source are removed, the foam will extinguish.

Melamine foam, like Mega Zorbe Hydrophobic Melamine Foam (HMF), can be used in combination with traditional materials, but can also be used alone as a self-supporting insulation with little to no fasteners. Easier to install than materials like fiberglass/mass loaded vinyl/jute/closed cell foam, Melamine Foam with self adhesive high temp backing decreases manufacturing time and labor costs, all without sacrificing sound absorption, thermal insulation, or fire resistance.
