Melamine foam, also known as nano-sponge, melamine foam, melamine sponge, high-tech foam, etc., is a flexible open foam that is made of safe melamine as a raw material and is made of high-temperature foaming. Its chemical structure and three-dimensional network cross-linking system make it have unique chemical and physical stability. It will not age and decompose under weak acid and weak alkali environment, and there is no residual free formaldehyde. Its hygienic properties can meet food hygiene requirements.

Melamine foam mesh structure

      Melamine foam is a new type of foam with a high opening ratio of three-dimensional grid structure. It has excellent sound absorption, flame retardancy, heat insulation, moisture and heat stability, hygienic safety and good secondary processing. Such as comprehensive performance. These characteristics make melamine foam products produced by Xiamen Sihang sponge manufacturers widely used in construction, vehicle manufacturing, factory construction, thermal engineering, equipment installation, air conditioning systems, aerospace navigation, electronic products, biological pollution control projects, and Use areas such as cleaning.

      ◆ Sound absorption

      The melamine foam fully open-hole three-dimensional grid structure system (opening rate of melamine foam with a density of 6kg/m3 is over 97%), so that the sound wave can enter the deep layer of the foam conveniently and efficiently, and transform into a grid. Vibration can be consumed.

Melting properties of melamine foam mesh structure

      ◆ Thermal insulation

      The three-dimensional grid structure of melamine foam enables the effective convection heat transfer of air, combined with its unique thermal stability, making it an irreplaceable lightweight thermal insulation material. The thermal conductivity is 0.036.

     ◆ Flame retardant

      Melamine foam can reach GB/T8624-2006 Grade B, DIN5510 S4 grade, B56853, UL94 V-0 grade without adding any flame retardant medium. In the case of open flame decomposition carbonization without generating droplets, smoke density<15. The book ""Fire Safety and Flame Retardant Technology in Public Places"" edited by the Ministry of Public Security is recommended as the preferred flame retardant material for public places.

Fire resistance of melamine foam mesh structure

      ◆ Thermal stability

      Melamine foam is a thermosetting plastic with a high degree of three-dimensional network cross-linking structure with high thermal stability and aging resistance. Melamine foam can work under long-term conditions of -180 ° C - + 200 ° C.

      ◆ Good post-processability

      The foam of Xiamen Sihang melamine foam can be conveniently processed into sheets, profiled materials by means of machining, and sound-absorbing products which are processed into a tapered and tapered shape to meet the sound absorption requirements.

      The melamine foam 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.

      Melamine foam 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.

      ◆ Light weight

      Melamine foam is currently the world's lightest foam, 4-12 kg / cubic.
