Hydrophobic melamine foam (with self-adhesive backing and without) is an enhanced product of melamine foam with excellent water resistance while maintaining all other sound absorbing properties (99.1% hydrophobicity after special treatment).
Hydrophobic melamine foam is very lightweight (6-7 kg/m3) and is elastic. The open surface allows sound waves to penetrate the foam and is not reflected as an echo. Used for sound insulation and insulation in aircraft, aerospace, marine, automotive and construction applications.
The principle of melamine foam absorption:
Due to the lower density of melamine sponge (4-12KG / m, open rate fand) reaching 97%, the three-dimensional grid system (L / D phase grid length to diameter ratio of about 10-20) deep sound can be fast and effective Entering the foam and converting it into a mesh vibration is consumed, effectively eliminating the radiated sound. These two rebounds reduce the sound. The ordinary foam is generally a semi-open structure, and the opening ratio is low, and a semi-closed pore structure occurs, and the semi-opening structure may seriously affect the sound insulation performance.
Product performance
Lightweight and flexible materials;
Floating in the water indefinitely; the water flows on the surface and rolls off.
Meets all aircraft (FAA, BSS, etc.), HVAC, automotive and transportation (railway) flame retardant, smoke and toxicity standards.
Application areas: ship or ship thermal insulation, hull compartments, doors, ship apartment decoration, machinery, bridges, cabins or cabs.
