Melamine foam is a new type of melamine foam with a high open porosity three-dimensional grid structure. In addition to excellent sound absorption performance, melamine has broad development prospects in the automotive industry due to its high heat insulation, high fire safety, high atomization performance, high chemical resistance, environmental protection and light weight. Melamine has reliably met the maximum flame propagation speed requirements in all fire tests conducted to date.
The laminated sound absorbing device produced by melamine foam is very suitable for the underside of the hood of the automobile, and can also be used for the installation of the cover and the transmission pipe in front of the end wall of the vehicle body.
Compared with other sound absorbing materials, melamine foam as the core part can output relatively high bending strength, reducing wear on the joints. Due to its excellent composite properties, the sound-absorbing and heat-insulating foam board made of melamine foam and aluminum foil is also used for the sound-absorbing use of the engine compartment of the car. The inlaid interior parts made of melamine foam reduce the noise in the cab. level. Melamine foam is combined with a composite heat shield made of aluminum foil and a sun visor made of melamine foam.
Melamine foams can be molded together with felts, fibers, metal foils and plastic films to form contour-filled parts for sound insulation, insulation and silencers. Good to meet the growing demand for sound insulation in auto parts.
Melamine foam is also used as a filler in the automotive industry due to its elasticity, light weight and excellent acoustic properties. The acoustic properties of the inserts made with melamine foam reduce the noise level in the truck cab and agricultural machinery. Therefore, such inserts make an important contribution to protecting the health of the operator and improving road safety.
Melamine foam is mainly used in rail vehicles for car wall filling, ceiling systems, air conditioning ductwork, car baffles, seats, etc.
