Sound attenuation melamine foam
customized
outstanding sound absorption effect
Sound Attenuation and Sound Insulation
It has outstanding sound absorption effect,Melamine foam has inherently flame retardant, high temperature stable and flexible. The length-to-diameter ratio of the grid is about 10 to 20, and its extremely high opening ratio characteristics (the opening ratio of melamine foam with a density of 4-12 kg/M3 is over 97%). Sound waves can easily and efficiently enter the deep layers of the foam and transform into vibrations of the mesh that can be consumed and absorbed, and effectively eliminate the reflected waves, especially the absorption characteristics of low frequency noise. The absorption characteristics of low frequency noise exhibited by melamine foam have aroused great interest in the acoustic field and have begun to be used more widely.
Acoustic performance: melamine sponge under the microscope is an irregular three-dimensional grid structure system, and it is a connected three-dimensional network structure, which greatly reduces the flow resistance of the air, so that the sound wave enters the foam quickly and efficiently and is transformed into a mesh vibration. Consumed to effectively eliminate radiated sound. The density of melamine sponge is only 8kg/m3, and the opening ratio is as high as 97%. A large number of connected cavities are the guarantee of sound absorption performance.
Flame Retardancy: The melamine sponge raw material is a flame-retardant amino thermosetting resin. It can reach GB/8624 - 2012 B1, DIN5510 S4, B56853, UL94 V-0 without adding any flame retardant medium. In the case of open flame decomposition carbonization without generating droplets, the density of smoke <15.
Insulation: Green, energy saving, environmental protection, sustainable development is the mainstream of the contemporary construction industry. The three-dimensional grid structure of melamine sponge effectively reduces the convective heat transfer of air, combined with the unique thermal stability. It has become an irreplaceable lightweight thermal insulation material with a thermal conductivity of only 0.036.
Good post processing performance: The melamine foam can be easily processed into a sheet, a profiled material by machining means, and a sound absorbing product which is processed into a tapered and tapered shape to meet the sound absorption requirement. The sheet can be made into a embossed acoustical ceiling and coil by hot pressing, while the surface strength is improved. It is easy to dye and is made into a colorful hanging sound absorbing material. It can be easily combined with metals, textiles, non-woven fabrics and other materials to produce a series of sound-absorbing and thermal insulation products to meet the needs of different places and working conditions.
These characteristics make melamine foam a new high-quality material that improves the noise immunity, safety and energy saving of vehicles. The melamine foam sheet can be made into a embossed acoustical ceiling and coil by hot pressing, while the surface strength is improved.
Melamine foam is widely used in construction venues, vehicle manufacturing, factory construction, equipment installation, air conditioning systems, aerospace navigation, defense industry, mechanical and electrical products, etc. Product size can be customized according to customer requirements at lfsponge.com.
