Sound absorbing material made of melamine resin foam. It can be cut, pasted, or hollowed out according to the shape and situation of the place where you want to absorb sound. Due to its high sound absorption and heat insulation performance, light weight and ease of processing, it is used in various general industries and construction fields such as bullet trains, automobile interiors, and aircraft.
Because it is a sound absorbing material, it is effective for high sounds (high frequencies), but it can also handle low to medium to high sounds by combining with other products such as aluminum fiber materials.
Example of use: Exhaust duct silencer, inside of equipment such as compressors and outdoor units, echo suppression in offices, rooms, studios, etc.
[Features]
➀ Sound absorption structure
A melanin resin foam with a dense open cell structure that exhibits excellent sound absorption performance. *Sound absorption performance is shown in the photo below.
➁ Lightweight
High density: Approximately 9 kg/m3, it is very lightweight and has excellent flexibility, making it easy to install. It can also be used to draw an arc.
➂ Flame resistance
It is self-extinguishing and exhibits high flame resistance (UL94 V-0).
④ High heat resistance and cold resistance
It can withstand a normal temperature of 150°C. (It maintains its flexibility even at extremely low temperatures.)
➄Chemical resistance
Unlike urethane foam, it does not crumble due to hydrolysis. *Detailed chemical resistance is shown in the table below.
⑥Weather resistance
No discoloration or deterioration due to UV rays.
⑦ Workability
It can be easily cut with a cutter or the like. Since it is easy to cut out, it can be constructed according to the shape of piping.
⑧Insulation
Thermal conductivity is 0.035W/m・k, which is almost the same insulation performance as glass wool.
⑨ Safety
There is no irritating odor that affects the human body, no scattering of fine pieces during cutting, no adverse effects on the eyes and throat, no irritation on the skin, and no discomfort during processing. In addition, unlike glass wool, there is no concern about the impact on the human body due to scattering due to aging after installation.
