The acoustic components coated with aluminum foil or waterproof non-woven fabric are used in the aircraft engine cabin noise processing. Aircraft supporting manufacturers have used melamine foam to fill airline seats, in addition to the use of its excellent absorption and flame retardant properties, containing melamine foam airline seats are much lighter than traditional seat. Using so many seats on a passenger plane adds up to a lot of weight loss. According to the aircraft manufacturer, due to the seat of 50% ~ 70% reduction in weight, save fuel prices two months can change offset the cost of the seat, it brings to the airlines both economic and environment benefits. The low - density and high - absorption properties of Yadina mylamine foam make it useful in aviation. The acoustical components of Yadina mylamine foam coated with aluminum foil are applied to the payload area of the rocket launcher. Such Settings can reduce acoustic pressure, which can protect highly sensitive instruments, such as satellites, in transport. The acoustic components coated with aluminum foil or waterproof non-woven fabric are used in the aircraft engine cabin noise processing. Yadina melamine foam material as a kind of low density thermal noise reduction (0.034 w/(m.k) thermal conductivity, flame retardant B1 level), has been widely applied in aviation seats, passenger ship, warship nacelle, low temperature gas carrier.the cabin and satellites, etc. The ultra-light properties of adinimine foam (6-12kg/m cubed) reduce the overall cabin weight while reducing noise. As a non-fiber product, no fiber will fall off during the flight. Melamine foam filled inside the cabin cavity, effective heat insulation effect, high-temperature and low temperature - 200 °, 240 ° can maintain its elasticity, is an excellent aircraft noise insulation materials.
