The melamine foam/melamine foam is made of high-temperature foaming of melamine resin without residual free formaldehyde; its stable chemical structure and cross-linking system make it unique chemical stability. Melamine foam is a new type of foam with a high open-cell three-dimensional grid structure. It has excellent sound absorption, flame retardancy, heat insulation, moisture and heat stability, hygienic safety and good secondary processing. Comprehensive performance.

Vehicle noise is one of the important indicators for evaluating car quality. The reduction of internal noise of the vehicle will greatly improve the comfort of drivers and passengers. The noise in the car is mainly from the vibration of the engine, the friction between the wheel and the ground, the howling of the air and the resonance of the car body. In addition to measures to improve the rigidity of the chassis and eliminate the low-frequency resonance zone, it is mainly eliminated by isolation and absorption. From the point of view of energy conservation, the materials required are lightweight; from a safety point of view, the materials are required to have fire and heat resistance properties. The advent of melamine foam and its various multifunctional composite materials has made it possible to improve the noise immunity, safety and energy saving of vehicles, especially in the automotive field.

1. Melamine foam is used in vehicle construction

 In addition to the excellent acoustic properties of melamine foams, the high thermal insulation, high fire safety, high atomization, high chemical resistance, environmental friendliness and light weight of the products are more and more valuable in the automotive industry.

Melamine foam can ideally meet the growing demand for sound insulation in vehicle manufacturing. Xiamen Sihang melamine foam can be molded into felt-like fittings with felt, fiber, foil and plastic. It can be used for sound insulation, thermal insulation parts and silencers.

Automotive industry application of melamine foam/melamine foam

Due to its elasticity, light weight and excellent acoustic properties, melamine foam is also used as a filler in the automotive industry. 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.

In addition to the excellent acoustic properties of melamine foam, its high thermal insulation, high fire safety, high atomization, high chemical resistance, environmental friendliness and light weight are highly desirable in the automotive industry. value.

Xiamen Sihang melamine foam is widely used in the sound insulation of automobile engine compartment cover, and can also be used as a cover in front of the body end wall and in the transmission lane. Since the parts provided with the material of the melamine foam can withstand relatively high bending stress-bending strength, the reduction in wear of the joint can be achieved compared to other sound absorbing materials, and the fastener can be saved.

In addition, melamine foam has other uses in the automotive industry, and the automotive profiled parts formed by hot pressing with aluminum foil, such as composite insulation boards made of melamine foam combined with aluminum foil, and through melamine foam Sun visor made of cotton inserts.

Due to the elasticity (memory effect), low weight and excellent acoustic properties of melamine foam, melamine foam is also used to fill cavities in the automotive industry.

3. Melamine foam is applied to rail vehicles

In terms of rail vehicles, the excellent acoustic properties and fire safety characteristics of melamine foam are destined to play a role in the wall and roof support as well as in the decorative interior trim of the laminate.

The strong thermal insulation properties of Xiamen Sihang melamine foam in the application of sidewalls and ceilings are another major advantage. As a result, the operating cost of the air-conditioned passenger car and the like can be significantly reduced. For example, the operating cost of an air-conditioned passenger car can therefore be greatly reduced.

Because of its light weight compared to other insulating materials, melamine foams also increase energy efficiency in transportation services. In addition, the weight of the vehicle wall and the top of the car is reduced, which lowers the center of gravity of the vehicle and thus improves the safety of the curve during operation. This is for narrow-gauge orbital roads (domestic maglev trains, EMU trains, urban rails) Trains are especially important.
