  • Rails Acoustics

Melamine Foam performs great acoustic insulation to medium- and high-frequency noises. According to the Noise Reduction Co-efficiency (NRC), the melamine foam insulates most noises between 250-4000Hz. Processed with plastics, felts, nonwoven cloths and metal shells, melamine foam also reduce low frequency noises.

FoamTech sound proofing foam is also widely applied in high-speed rails, light rails and subways. The Melamine Foam is installed in cavity wall insulation, acoustic foam tiles, seats and sound proofing foam for engine peripheries.

Acoustic foam tiles have outstanding performance in acoustic insulation, comparing with conventional materials, it also has the lowest density(0.375-037lb/ft3), which decreases the whole vehicle weight, and increases the safety of turning and reduce energy consumption.

acoustic foam tiles performance

Melamine acoustic foam meets the fire retardant requirements for vehicles and rails. Melamine foam is made of the melamine resin. When it comes to fire, melamine foam generates nitrogen gas, which isolates the surface from the oxygen and thus prevents further burning.
